Jera Line is excited to announce that our shearhead long palm lug CLB-2K-VzT-36-2-16-95 has successfully passed the full IEC‑61238‑1 type test program by the third party in dependent accredited Laboratory.

A utility‑grade, type‑tested connection solution for medium‑voltage cable terminations. Jera Line’s 2‑hole shear‑head cable lugs deliver reliable electrical performance, controlled installation torque, and long‑term mechanical stability—validated by IEC‑61238‑1 testing.

Product overview of Cable lug with 2 shear-head bolts CLB-2K-VzT-36-2-16-95

The CLB‑2K‑VzT‑36‑2‑16‑95 is a high‑performance mechanical cable lug designed for 16–95 mm² aluminum or copper conductors. Equipped with two shear‑head bolts, this lug ensures controlled torque, and reliable electrical contact without the need for crimping tools.

Key Features

• Shear‑head bolt technology: Provides controlled torque and uniform compression for repeatable, error‑resistant installations.
• 2‑hole centered palm: Ensures stable mounting, improved mechanical support, and optimal alignment with equipment terminals.
• Low contact resistance: Precision machining and surface treatment deliver reliable conductivity and reduced thermal rise.
• Corrosion‑resistant materials: Tin‑plated aluminum body for harsh outdoor and industrial environments.
• Al/Cu conductor support: Compatible with both aluminum and copper conductors for flexible deployment.
• Type‑tested performance: Verified to IEC‑61238‑1 for electrical and mechanical reliability.

IEC‑61238‑1 Type Test Scope

Jera Line is a manufacturer of shearhead torque lug for 16-95 mm² conductors. Our products have successfully passed all required electrical and mechanical tests in accordance with IEC‑61238‑1, demonstrating their reliability and suitability for medium‑voltage applications.

Electrical Type Tests

• Temperature Rise Test: Validates stable electrical performance and low resistance under continuous rated current.
• High‑Current Cycling: Confirms long‑term conductivity and the connector’s ability to withstand repeated thermal expansion and contraction.
• Contact Resistance Measurement: Ensures consistently low resistance at the conductor‑to‑lug interface for dependable electrical performance.

Mechanical Type Tests

• Conductor Pull‑Out / Retention Test: Verifies the connector’s gripping force and ensures the conductor remains securely fixed under mechanical load.
• Shear‑Head Bolt Torque Validation: Confirms proper shear‑off performance at the calibrated torque level, guaranteeing uniform compression during installation.
• Vibration and Thermal Cycling Resistance: Assesses the connector’s ability to maintain mechanical stability under temperature fluctuations and operational vibration.
• Mechanical Strength and Structural Integrity: Demonstrates the lug’s robustness during installation and its long‑term durability in service conditions.

Passing all these tests confirms that the CLB-2K-VzT-36-2-16-95 shearbolt lug meets the highest standards for utility‑grade MV connectors.
