Overview

We manufacture Aluminum Hot Line Clamps—also referred to as Hotline Clamps, Live-Line Clamps, or Hot Tap Clamps—for overhead electrical distribution systems used across the United States. We are a leading manufacturer of hotline clamps, casting foundry offering hotline clamps, Aluminum Hotline Clamps, bronze Hotline clamps from India.

These clamps are designed to create secure electrical and mechanical connections on energized conductors, allowing utilities to perform tapping, maintenance, and emergency restoration without interrupting power supply.

Built for USA utility supply chains, our clamps combine high-conductivity Aluminum alloy bodies, hot-stick-friendly operating hardware, and export-grade quality control.


Common Names Used in the USA

  • Aluminum Hot Line Clamp

  • Hotline Clamp

  • Live-Line Clamp

  • Hot Tap Clamp

  • Distribution Line Tap Clamp


What Is an Aluminum Hot Line Clamp?

An Aluminum hot line clamp is a connector used to temporarily or semi-permanently tap or connect overhead conductors while the line remains energized.

It is operated using live-line tools (hot sticks) and is widely used by electric utilities to:

  • Avoid service interruptions

  • Perform maintenance safely on live lines

  • Install temporary or emergency connections


Typical Applications

Utility Distribution

  • Live-line tap connections

  • Temporary bypasses during maintenance

  • Switching and sectionalizing operations

  • Emergency restoration work

Substation & Renewable Systems

  • Temporary connections during upgrades

  • Wind and solar collector circuits

  • Field service work where downtime is critical


Design Features

High Conductivity

  • Aluminum alloy body for efficient current transfer

  • Outdoor-service surface finish

  • Stable electrical contact under load

Live-Line Friendly Operation

  • Eye / bail design compatible with hot sticks

  • Smooth operating surfaces

  • Consistent thread quality for controlled tightening

Mechanical Stability

  • Secure clamping action

  • Resistance to loosening under vibration

  • Designed for overhead service conditions

OEM Customization

  • Private labeling and part marking

  • Customer-specific part numbers

  • Distributor and utility packaging options


Materials & Construction

Body of Aluminum Hotline Clamps

  • High-conductivity Aluminum alloy

  • Cast or forged depending on model design

Operating Hardware (as per customer specification)

  • Bronze

Final material combinations are confirmed per model and utility specification.


Models & Size Ranges

We manufacture multiple Aluminum hot line clamp configurations commonly used in USA distribution systems.

Common Model Families of Aluminum Hotline Clamps

  • Universal hot line clamps (wide conductor range)

  • Eye-type hot line clamps for hot-stick operation

  • Tap-style and parallel-groove variants (application-specific)


Technical Torque & Conductor-Range Table (Typical – USA Practice)

Note: Final torque values depend on bolt diameter, material, coating, and utility specification.
Values below are industry-typical guidance only and must be verified against approved drawings.

Clamp Size Category Run Conductor Range Tap Conductor Range Typical Bolt Size Typical Installation Torque*
Small #6 AWG – 1/0 AWG #10 AWG – 2 AWG 3/8″ 20–25 ft-lb (27–34 Nm)
Medium 1/0 AWG – 4/0 AWG #6 AWG – 1/0 AWG 1/2″ 35–45 ft-lb (47–61 Nm)
Large 4/0 AWG – 336.4 kcmil 1/0 AWG – 4/0 AWG 5/8″ 55–70 ft-lb (75–95 Nm)
Extra-Large 336.4 – 795 kcmil 4/0 AWG – 336.4 kcmil 3/4″ 75–95 ft-lb (102–129 Nm)

Aluminum vs Bronze Hot Line Clamps (For USA)

Utilities often ask when to use Aluminum versus Bronze hot line clamps. The choice depends on conductor material, duty cycle, and long-term installation intent.


Material Comparison Table

Parameter Aluminum Hot Line Clamp Bronze Hot Line Clamp
Primary Use Temporary or semi-permanent live-line taps Permanent live-line connections
Conductivity Good (matches aluminum conductors) Excellent
Weight Lightweight Heavier
Cost Lower Higher
Corrosion Behavior Suitable for aluminum-to-aluminum Excellent, especially in harsh environments
Typical Use Case Maintenance, emergency restoration, temporary taps Long-term taps, substations, critical circuits
Galvanic Compatibility Best with aluminum conductors Excellent with copper or ACSR steel core

When to Choose Aluminum Hot Line Clamps

  • Temporary or emergency connections

  • Maintenance operations

  • Aluminum-to-aluminum conductor interfaces

  • Cost-sensitive utility programs

  • Situations requiring lightweight handling


When to Choose Bronze Hot Line Clamps

  • Permanent installations

  • Substations and high-reliability circuits

  • Mixed-metal conductor systems

  • High corrosion or coastal environments

  • Applications requiring maximum mechanical strength


Why Utilities Use Both

Many USA utilities specify both Aluminum and Bronze hot line clamps depending on:

  • Location (overhead line vs substation)

  • Duration of installation

  • Environmental severity

  • Long-term reliability requirements

We support  both material options, with model-by-model guidance to ensure correct selection.


Safety Note

Hot line clamps are intended for use by trained personnel using approved live-line procedures and tools. Installation must follow applicable utility safety standards and torque guidelines.
