Product Description

Exposed or weak lugs can spark power loss and safety issues over time. Our lugs tie conductors with strength and insulation material like PVC, ensuring steady performance and lasting security for your critical setups. 

Barrel Length

Extends 10 mm to 30 mm, ensuring secure crimping with insulated coverage

Termination Type

Features single-hole stud setup; stud sizes from 4 mm (M4) to 12 mm (M12) for fastening

Crimping Compatibility

Fits hexagonal, indent, or circular tools; suits manual or hydraulic crimping methods

Operating Temperature Range

Works from -40°C to 105°C, performing well in varied thermal conditions

Color Coding

Uses red, blue, yellow markings, simplifying size identification for quick use

Voltage Rating

Supports up to 600 V, ideal for low to medium voltage systems (insulation-dependent)

Tensile Strength

Delivers 400 N to 2500 N, maintaining firm mechanical grip under stress

Environmental Resistance

Boasts IP54 rating; resists moisture and dust with insulated protection

Standards Compliance

Meets IEC 61238-1, UL 486A-486B, and RoHS, ensuring safety and performance

Installation Method

Applies crimp-on technique; designed for standard crimping tools

Conductor Compatibility

Compatible with Class B/C stranded copper, aluminum (AA-1350), and tinned marine cables

Technical Advantages

Bare or loose connections in active setups can cut efficiency and spark repair costs. Our Insulated Copper Lugs feature color coding in red, blue, and yellow to simplify sizing and hold conductors tight with strong crimping compatibility for top safety. 

Unprotected joints or wrong fits can weaken systems and stall output under load. Our lugs work across a wide temperature range and resist moisture with solid environmental protection, keeping joints secure every time.

Industry Applications

Automotive Assembly

Locking power to harnesses keeps assembly lines moving and production flowing without breaks even under high demand.

Solar Power Systems

Connecting panels to grids maintains energy steady and generation strong through shifting weather conditions.

Factory Machinery

Heavy tasks need cables secured in motors to push production ahead and keep equipment running without stops. 

Control Panels

Linking circuits in panels holds power stable and supports smooth facility operations across busy layouts. 

Cooling Units

Tying compressor lines firmly sustains HVAC systems and handles tough loads in key environments. 

Railway Signals

Safe networks rely on fastening cables in signaling to ensure steady communication and back vast rail lines.

Steady Connections for Demanding Systems

Unshielded terminations in tough applications can halt workflows and lift maintenance expenses. Our Insulated Copper Lugs handle heavy currents and offer insulation thickness for safety, keeping your systems steady under harsh conditions with lasting crimp seal integrity. 

Failing connections can harm parts and push replacement budgets higher. Our lugs, made from pure copper and fitting varied stud sizes, maintain control, cut downtime, and ease your costs.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How do insulated lugs cut safety-related costs in my production lines?

Our Insulated Copper Lugs shield connections with strong insulation material like PVC, reducing risks of shorts or shocks that drive up liability expenses. This protection keeps workers safe and lowers insurance claims, saving your budget over time. Plus, the secure fit ensures steady output without costly interruptions. 

What prevents crimping errors from slowing my assembly process?

Featuring color coding in red, blue, and yellow, our lugs simplify size matching to avoid wrong crimps that stall production. The barrel design supports even pressure with standard tools, ensuring joints hold firm without rework. This efficiency speeds up assembly and keeps your timelines on track. 

Why might bare lugs raise my maintenance expenses in damp conditions? 

Exposed lugs corrode faster in moisture, but our Insulated Copper Lugs resist wear with solid environmental protection and finish options like nylon. This durability cuts replacement frequency, trimming your maintenance costs in wet settings. As a result, your systems stay operational longer without extra spending. 

Can weak insulation limit my system’s power efficiency over time?

Our lugs maintain steady power with high-conductivity copper and thick insulation to prevent leakage that saps efficiency. This strong setup reduces energy waste, keeping your operational costs down through heavy use. In turn, your equipment performs consistently without draining profits.

How does lug insulation impact my safety compliance audits?

Meeting IEC 61238-1 and UL 486A-486B standards, our Insulated Copper Lugs offer robust dielectric coverage to pass strict safety checks. This compliance avoids audit penalties and rework, saving you time and expense on certifications. Plus, the insulated design boosts worker safety, strengthening your compliance record.
