Technical Characteristics & Design
For 12 to 24kV applications the 17-24JTS heat shrinkable joint is the new high performance, compact and easy to install joint. A single body with all the electrical functions integrated!
The JTS 17/24 is using Nexans’ “TRIPLE GT125”, an integrated stress control field, insulating and conductive tube, which can withstand high voltage applications up to 24kV.
A double layer pad with conductive rubber inside and HK orange mastic outside ensure a Faraday cage and smooth the effect of the electrical field and of the voltage gradient in the connector area.
The electrical continuity of the screen is ensured with a standard metallic tape plus earthing ferrules (CW type) while for tape screen, an additional earthing braid is provided (AW type).
The outer sheath is restored with heavy/ medium wall adhesive lined tubing. Vapor barrier protection is available upon request. MC types are supplied with “Nexans GPH” mechanical connectors.
