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.
A standard metallic tape and earthing ferrules (CW type) ensure the screen’s electrical continuity, while an additional earthing braid (AW type) comes with the tape screen.
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.
