STT-15kV-200A Rotatable Feedthru Insert

General Information

15kV 200A double-pass sleeve connector, connected with the sleeve socket to achieve single- way and double-way conversion, one of which has the same function as the single-pass sleeve connector, the other link elbow arrester (to provide over voltage protection), or to change the connection mode of the box transformer.

This product is mainly used for high voltage electrical equipment such as American box transformer, outdoor ring switch cabinet and so on. Common cable accessories connected with it are: elbow type connector, elbow type lightning arrester and sleeve seat.

Adopting high quality EPDM rubber insulation, advanced design structure of double sleeve ensures normal arc extinguishing when disconnecting from elbow joint.

Unique release and inversion design ensures that the double-way casing joint rotates to the proper installation position without affecting its connection performance.

Product Structure

1.EPDM INSULATION:High-quality sulfur-cured EPDM insulation is mixed and formulated in-house for consistent and reliable field performance.

2.INTERFACE THREADS: 3/8″-16 UNC Threads.

3.TORQUE-LIMITING RATCHET: Eliminates bushing well stud breakage and allows for 360° orientation.

4.SEMI-CONDUCTIVE SHIELD: Molded semi-conductive sulfur-cured EPDM shield meets requirements of IEEE Standard 592™.

5.LATCH INDICATOR RING: Molded-in bright yellow ring eliminates elbow installation guesswork by assuring a quality connection.

6. COPPER BUS BAR: Provides reliable all copper current path and ensures the coolest operating temperatures.
7. ARC SNUFFER ASSEMBLY:Arc-ablative plastic produces arc extinguishing gas during loadbreak switching operations.
8. LOCKING GROOVE: Nose piece locking groove is made of high strength, high temperature plastic that secures mating connector to feedthru insert.
