IEC 61238-1 tested factory it means Jera Line factory is a qualified factory who produce mechanical cable lugs, the shear head cable lugs are verified for safety, reliability, and long‑term performance.

About the Shear Head Cable Lug CLBVzT‑36‑2‑70‑240

The CLBVzT‑36‑2‑70‑240 shear head cable lug is engineered for 70–240 mm² aluminum and copper conductors. It is designed to provide a stable, low‑resistance, and long‑lasting electrical connection without the need for crimping tools, making installation faster, safer, and more consistent.

Key features:

• Wide conductor range: 70–240 mm²
• Shear‑head bolts with torque zone for controlled tightening and consistent electrical contact
• Tin‑plated aluminum body for both AL and CU conductors
• Fast and convenient Installation
• Suitable for low‑ and medium‑voltage distribution networks
• Proven reliable performance in harsh environments
• Manufactured in Jera Line’s modern factory in China

IEC‑61238 Type Test: Ensuring International‑Standard Performance

The IEC 61238‑1 type tests—the international standard that evaluates the electrical and mechanical performance of mechanical cable connectors used in low‑ and medium‑voltage power distribution.

The tests including:

1. Electrical Testing (IEC 6123813:2018, Clause 6)

• Temperature rise limits
• High‑current cycling
• Electrical stability under load

These tests ensure the lug maintains low resistance and stable performance throughout its service life.

2. Mechanical Testing (IEC 6123813:2018, Clause 7)

This includes:

• Mechanical strength
• Conductor retention capability
• Long‑term durability under mechanical stress

Successful results demonstrate that the connector can withstand installation forces, vibration, and long‑term operational loads.

Mechanical cable lug was produced in an IEC‑61238 Type Tested Facility — Jera Line

With the successful certification IEC-61238 of cable lug CLBVzT-36-4-70-240, Jera Line continues to expand its portfolio of medium-voltage lugs that support safe, efficient, and standardized power transmission across global markets.

This achievement reinforces our commitment to manufacturing high‑quality, internationally compliant connection solutions for modern power distribution networks.
