EEP-12-4000-50 12kV Vacuum Interrupter embedded poles

Description:

Model No.:EEP-12/4000-50,12kV vacuum interrupter embedded poles apply on circuit breaker,switchgear

  • Product Description

EEP-12-4000-50  12kV vacuum interrupter embedded poles apply on circuit breaker,switchgear

Vacuum interrupter embedded poles with epoxy resin,is made by casting vacuum interrupters,main circuit conduct and mounting parts with epoxy into an integral part. The vacuum interrupters, however,should be enveloped well with a slight fold of silicon rubber jacket before that process.
