Product Overview
COMPAQ INTERNATIONAL presents the CHJ Series — an advanced range of heat shrinkable straight through cable jointing kits engineered for 1-core and 3-core polymeric insulated cables (XLPE/EPR) up to 42kV. These medium voltage (MV) cable joints are built to deliver exceptional performance, rapid installation, and long-term reliability across a wide range of utility, renewable, and infrastructure applications.
Whether in substations, solar farms, or underground cable networks, our heat shrink joints simplify the jointing process while upholding international quality and safety standards.
COMPAQ’s proprietary cross-linked materials ensure secure insulation, effective stress control, and reliable environmental sealing. The design reduces the risk of air entrapment and improves dielectric performance—without the need for hazardous heating tools.
Designed for maximum adaptability, the CHJ Series is suitable for various medium voltage cable constructions, including copper and aluminum conductors, wire or tape screen configurations, and armored or unarmored types (SWA/AWA).
Compatible with both compression and mechanical (shear bolt) connectors, allowing installers to select connection methods based on site preferences or retrofit conditions.
Engineered to deliver stable electrical and mechanical characteristics even under elevated thermal or load conditions. Each joint undergoes rigorous testing for insulation resistance, partial discharge, and impulse withstand voltage.
The simplified heat shrink assembly process speeds up on-site execution, minimizes human error, and reduces overall labor requirements.
Built to withstand outdoor and underground environments, the CHJ joints are UV-stable, water-tight, and resistant to chemicals and pollution—ensuring long-term reliability.
When stored in recommended conditions, all components maintain their performance properties indefinitely, supporting bulk procurement and efficient stock management for utilities and EPC contractors.
Successfully deployed in thousands of medium voltage installations across more than 40 countries, the CHJ Series is trusted by engineers, utilities, and contractors worldwide.

A heat shrink straight through joint is used to connect two sections of medium voltage power cables in a straight line. The joint uses heat-activated materials that shrink tightly around the cable, providing electrical insulation, mechanical protection, and environmental sealing.
COMPAQ’s CHJ Series is designed for medium voltage applications up to 42kV. It is suitable for a wide range of cable sizes and constructions across 1-core and 3-core XLPE or EPR insulated cables.
Yes. The CHJ Series is fully compatible with compression (crimped) and mechanical (shear bolt) connectors, providing flexibility for different project requirements and site conditions.
Absolutely. The CHJ Series is tested for outdoor, underground, and harsh environmental conditions. The joints are water-resistant, UV-stable, and flame-retardant, making them ideal for diverse field environments.
The CHJ Series is manufactured and tested in accordance with:
The components of the CHJ Series have an unlimited shelf life if stored in proper, dry conditions. This helps reduce material wastage and supports long-term storage planning.
