Shielded angular head (COUPLING) for 20kV linear field to connect to RSTI, type RSTI-5851 (35-70), brand Raychem / TE Connectivity TE-CM0094 RSTI-CC-5851

Angled shielded head for gas switchgear

This shielded angled head (coupling) from Raychem / TE Connectivity, type RSTI-CC-5851, is designed for connecting 20kV line terminations and working with RSTI connectors. It is a key component in the construction and maintenance of medium-voltage gas-insulated switchgear, providing a safe and reliable cable connection. This head is particularly useful in situations requiring parallel connection of the same phase.

Design and application

The RSTI-CC-5851 head utilizes cold-shrink technology, which simplifies installation and ensures a durable connection. Its design allows for the construction of single, double and triple systems, offering flexibility in network configuration. It is compatible with C1 (630A) and C2 (1250A) type through insulators, increasing its range of applications. Thanks to the shielded body made of modified silicone rubber, the head minimizes electromagnetic interference and provides high resistance to atmospheric conditions. The ability to perform a voltage test on the jacket and cable insulation without disconnecting the head from the device is another feature that facilitates diagnostics and maintenance.

Key benefits for installers and users

• Simple installation: The slip-on technology significantly speeds up the installation process, reducing downtime and labor costs.
• Versatility: Compatibility with different types of through insulators and the ability to create multiple systems increase the range of applications for the head.
• Durability and reliability: Construction from high-quality materials guarantees long-lasting and trouble-free operation in various environmental conditions.
• Safety: The shielded housing minimizes electromagnetic interference, and the ability to perform a voltage test without disconnecting the head increases the safety of diagnostics.
