Overview

Our Raychem RSTI Screened Separable Connectors feature a compact design to fit in tight installation spaces, are fully shielded, submersible and available with optional test points.
TE´s Raychem screened seperable T-connectors

Our Raychem RSTI Screened Separable Connectors are designed to connect single and three-core polymeric cables to medium voltage gas insulated switchgear and other equipment using bushings Type “C” (EN 50180/EN 50181), specified for 630/1250A up to 42 kV. Made of a highly modified silicone rubber and protected by a thin-walled outer conductive screen connected to the earth, these screened separable connectors are equally suited for indoor and outdoor installation. Supporting a wide application range, the design incorporates one body and two stress cone adapters to cover all cross-sections from 25 to 1000 mm². The overall and cut-back dimensions are designed to take up minimum space in the terminal box. These connectors are equipped with a capacitive test point for determining whether the circuit is energized. This test point is protected by a conductive cap. After cable preparation and lubrication, the stress control adapter is simply slid into place, followed by the screened connector body. These two components can be installed under virtually any conditions. A separable mounting system ensures easy installation of the connector onto the bushing. All kits include high-performance multi-range mechanical or DIN compression lugs matching the design of the screened separable connectors.
