Product Overview – Bronze Hotline Clamps
1. Cast Bronze Clamp Body
The main clamp body is sand-cast from leaded tin bronze (LG2 / C83600) or gunmetal bronze, offering high electrical conductivity, excellent machinability, and proven resistance to atmospheric and electrochemical corrosion. The casting captures complex internal jaw geometry in a single pour, eliminating multi-piece assembly. Post-casting, the body undergoes CNC turning and milling to achieve precise jaw opening dimensions, seating profiles for bare conductor and ACSR conductors, and mounting-hole locations. Typical applications include overhead line tapping, jumper connections, T-connections, and temporary grounding points on energised or de-energised conductors from 11 kV distribution to 400 kV transmission systems. Related terms: bronze sand casting, gunmetal casting, LG2 bronze, C83600 alloy, CDA 836, powerline connector body, overhead line clamp, conductor tap clamp, line hardware casting.
2. Bronze Eyebolt
The Bronze Eyebolt is an integral operational component threaded into the clamp body, providing the hot-stick engagement ring for live-line installation and removal by qualified linemen using insulated tools. Cast and machined from the same bronze alloy family as the clamp body, the eyebolt delivers galvanic compatibility, eliminating the risk of bimetallic corrosion at the thread interface. The eye ring is machined to a precise internal diameter to accept standard hot-stick hooks specified in IEEE 1048 and IEC 60900. The thread form conforms to ISO metric or UNC standards as per customer specification. Related terms: hot-stick eye, live-line engagement eye, bronze eye bolt, lineman engagement ring, insulated-tool interface, hot-line tool hook, live working hardware, IEEE 1048 eyebolt, bronze fastener, clamp actuator bolt.
3. Stainless Steel Eyebolt Key
The Eyebolt Key is the locking/retention pin machined from Grade 304 or Grade 316 Stainless Steel bar stock. It passes through the clamp body transversely to retain the bronze eyebolt under the compressive and vibrational loads encountered during live-line operations and long-term service. Stainless steel is selected for this component due to its superior tensile strength, immunity to galvanic corrosion in contact with bronze, and resistance to stress-corrosion cracking in coastal and industrial environments. The key is retained by a cotter pin or formed-wire retainer to prevent accidental dislodgement during installation. Related terms: SS eyebolt retainer, stainless steel locking pin, grade 316 key pin, eyebolt retention key, anti-rotation key, corrosion-resistant fastener, cotter pin retainer, 316 SS hardware, lineman clamp key, bronze-stainless interface fastening.
4. Jaw Mechanism and Conductor Seating
The jaw assembly is designed to clamp securely onto overhead bare conductors — ACSR (Aluminium Conductor Steel Reinforced), AAC (All Aluminium Conductor), AAAC, and bare copper conductors — across a defined conductor diameter range. The jaw faces are machined with serrated or smooth profiles depending on application (permanent vs. temporary). A bronze or stainless-steel jaw bolt applies clamping force and is torqued to the manufacturer’s recommended value using a calibrated torque wrench. The jaw opening is pre-set at the factory and adjusted on-site. Related terms: clamp jaw mechanism, serrated jaw face, conductor seating groove, jaw bolt torque, bare ACSR clamp, AAC clamp, conductor diameter range, overhead line hardware, powerline clamp jaw, field-adjustable jaw opening.
5. Electrical Continuity and Contact Interface
Bronze hotline clamps provide a low-resistance electrical contact path between the conductor and the connected circuit (tap wire, ground lead, or temporary bypass cable). The machined contact surfaces on the jaw achieve a surface finish of Ra 3.2 µm or better, ensuring repeatable low contact resistance. Contact resistance is verified by the four-wire Kelvin method per ASTM B539 on production samples. The bronze alloy’s natural electrical conductivity (minimum 12–15% IACS for LG2 bronze) is sufficient for rated current-carrying duty in tap and ground applications. Related terms: low-resistance contact, electrical continuity clamp, contact surface finish, four-wire Kelvin test, ASTM B539, contact resistance measurement, tap connection clamp, current-carrying clamp, conductor-to-clamp resistance, temporary bypass clamp.
6. Surface Finish and Corrosion Protection
Standard supply is mill-finish bronze (natural oxide). Optional finishes include electro-tin plating (for low-contact-resistance tapping applications), clear lacquer coat (for storage protection), and hot-dip or electroless nickel plating for aggressive industrial atmospheres. The stainless-steel eyebolt key is supplied with a passivated finish per ASTM A967. All fastener hardware is either stainless steel or silicon bronze to eliminate incompatible metal contact. Related terms: mill-finish bronze, tin-plated bronze clamp, nickel-plated powerline hardware, passivated stainless steel, lacquer-coated clamp, corrosion-resistant hotline clamp, coastal environment hardware, silicon bronze fastener, anti-oxidation coating, electroless nickel bronze.

Manufacturing Process
Conex Casting follows a disciplined multi-stage manufacturing process for Bronze Hotline Clamps:
- Raw Material Verification: Bronze ingots (LG2/C83600) and stainless-steel bar stock are verified against MTCs. Optical emission spectroscopy (OES) confirms alloy chemistry before melting.
- Pattern Making and Mould Preparation: Precision sand moulds are prepared using resin-bonded silica sand. Core boxes for internal jaw geometry are assembled and inspected dimensionally before closing the mould.
- Sand Casting (Gravity Pouring): Molten bronze at 1,100–1,150 °C is poured into the prepared mould. Controlled pouring speed and riser design minimise shrinkage porosity. After solidification, castings are shaken out, cut, and shot-blasted.
- CNC Machining: Cast blanks are fixtured on CNC turning centres and machining centres. Jaw opening, eyebolt thread (ISO M or UNC), key-pin bore, and all seating surfaces are machined to drawing tolerances (±0.05 mm for critical features).
- Stainless Steel Key Machining: SS bar stock is turned and cross-drilled on CNC lathes. Passivation is carried out per ASTM A967 before assembly.
- Assembly and Torque Verification: The bronze eyebolt and SS key are assembled into the clamp body. Jaw bolt torque is verified. Captive hardware retention is checked.
- Inspection and Testing: Dimensional inspection (Vernier, CMM for critical batches), visual inspection for casting defects, contact resistance measurement (ASTM B539), and pull-out force test on the eyebolt assembly.
- Surface Treatment (if specified): Tin plating, nickel plating, or lacquer coat applied per customer specification.
- Marking, Packaging, and Dispatch: Each clamp is stamped with batch number and size code. Packed in inhibited poly bag, inner carton, and ISPM-15 export crate with MTC documentation.

Frequently Asked Questions (FAQ)
Q1. What is a Bronze Hotline Clamp?
A Bronze Hotline Clamp is a cast-and-machined powerline hardware fitting used to make a mechanical and electrical connection to an overhead conductor — either while the line is energised (hot-line / live-line operation) or de-energised. The bronze body provides corrosion resistance and electrical conductivity; the bronze eyebolt enables hot-stick tool engagement; the stainless-steel key locks the eyebolt securely in service.
Q2. What bronze alloy is used for the clamp body?
The standard alloy is LG2 Gunmetal Bronze (ASTM C83600 / BS 1400 LG2 / IS 318 Grade 2) — a leaded tin bronze (Cu 85%, Sn 5%, Pb 5%, Zn 5%) with excellent castability, machinability, and atmospheric corrosion resistance. Phosphor bronze (C51000) and aluminium bronze (C95400) are available on request for higher-strength or elevated-temperature applications.
Q3. What grade of stainless steel is used for the eyebolt key?
Standard supply is Grade 304 austenitic stainless steel (ASTM A276). Grade 316 (molybdenum-bearing) is available and recommended for coastal, marine, or industrial chemical environments where chloride-induced corrosion is a risk.
Q4. What conductor sizes do your Bronze Hotline Clamps cover?
Our standard range covers conductors from 10 mm² to 400 mm² cross-section (approximately 6 AWG to 750 kcmil), including ACSR Dog, Cat, Rabbit, Panther, Moose, and metric equivalents, AAC, AAAC, and bare stranded copper. Custom jaw profiles for non-standard conductors are available to drawing.
Q5. Can Bronze Hotline Clamps be used on live (energised) lines?
Yes — the bronze eyebolt is designed for hot-stick tool engagement per IEEE 1048 / IEC 60900, enabling installation and removal on energised overhead lines by trained and authorised live-line workers. The voltage rating depends on the specific clamp model and must be confirmed against the product datasheet before live-line deployment.
Q6. What is the minimum order quantity (MOQ)?
There is no strict MOQ for standard sizes. We accept orders from 25 pieces (sample/proto quantities) upward. For custom designs with new pattern/tooling, a minimum quantity covering tooling amortisation is discussed at the quotation stage. Contact us for specifics.
Q7. Do you supply Material Test Certificates (MTCs)?
Yes. Every shipment is accompanied by an MTC covering chemical composition (OES analysis) and mechanical properties (tensile, yield, elongation, hardness) of the bronze casting heat. Stainless-steel mill certificates for the eyebolt key are also provided. Third-party test reports from SGS, Bureau Veritas, or TÜV are available on request at cost.
Q8. What is the typical lead time?
For standard sizes from running stock patterns: 3–4 weeks from order confirmation. For new jaw sizes or custom designs requiring new patterns: add 3–4 weeks for pattern fabrication and first-article approval. Expedited production is available for urgent project requirements — contact our sales team to discuss.
Q9. What quality standard does your manufacturing facility hold?
