Product Overview
The COMPAQ CHJ Series for 66/72.5kV applications offers a robust and high-performance solution for straight through jointing of single-core XLPE insulated high voltage cables. Designed for power transmission systems, substations, and underground cable networks, this advanced jointing system ensures mechanical strength, electrical integrity, and environmental protection.
Fully tested in accordance with IEC 60840, the CHJ Series enables dependable connectivity in high-voltage networks while simplifying installation and minimizing project downtime.
Specifically designed for single-core and three-core XLPE-insulated cables used in transmission-grade networks, ensuring secure and consistent performance across long distances and critical installations.
Built to perform in diverse and extreme climates, including high-humidity, coastal, desert, and industrial environments—ensuring uninterrupted operation under environmental stress.
The pre-engineered jointing system enables quick and safe installation using standard tools—no hot work or hydraulic crimping required. This reduces on-site labour and installation time.
Multi-layer insulation with heat shrink tubing and sealing mastics provides excellent defence against moisture ingress and mechanical stress—delivering long-term operational reliability.
Compatible with both mechanical shear bolt connectors and compression lugs. Kits are supplied with tested and approved connectors based on project preferences—enhancing installation convenience.
Manufactured from high-grade heat shrink materials designed for long-term storage without performance degradation, enabling better inventory management and long-term readiness.
Fully type-tested and certified in accordance with IEC 60840, ensuring the joint’s suitability for high-voltage use in utility and infrastructure networks.
Successfully deployed in 40+ countries by leading utilities, EPC contractors, and transmission system operators—reinforcing trust in COMPAQ’s engineering and global reliability.
