JRSY-10 10 kV Heat Shrinkable Cable Joint Kit
JRSY-10 10 kV Heat Shrinkable Cable Joint for XLPE Power Cables
Product Application
JRSY-10 Series is designed for straight-through intermediate joints of 6/10 kV and 8.7/15 kV XLPE insulated power cables. It provides reliable electrical insulation, sealing and mechanical protection for distribution networks, industrial power systems and utility projects. The joints are suitable for both indoor and outdoor installations, and can also be used for the repair of damaged cable outer sheaths.
Product Features
• Heat shrinkable design ensures a tight fit and excellent interface between insulation layers
• Provides high-quality electrical insulation and robust mechanical protection for cable joints
• Optional adhesive-lined components offer enhanced moisture sealing and corrosion protection
• Good resistance to tracking, weathering, UV and common industrial chemicals
• Compatible with most 6/10 kV and 8.7/15 kV XLPE power cables
• Easy and safe installation with standard heating tools, suitable for on-site construction work
