36kV 1250A Epoxy Vacuum interrupter for Vacuum Circuit Breaker
The EP-36KV/1250-20 embedded poles are essential insulation and conductive components designed for medium and high-voltage vacuum circuit breakers. Manufactured with advanced epoxy resin APG technology, they encapsulate the vacuum interrupter and conductive parts, providing excellent dielectric strength, high mechanical reliability, and compact design. Suitable for switchgear with a rated voltage of 36kV, a rated current of 1250A, and a rated short-circuit breaking current of 20kA.
Key Features
1.Superior Insulation Performance - Epoxy resin embedded structure ensures high dielectric strength and safe operation.
2.Compact & Integrated - Vacuum interrupter and conductor embedded as one unit, easy to install.
3.High Mechanical Strength - Excellent resistance to heat, impact, and environmental stress.
4.Creepage Distance Design - Extended surface ribs improve pollution resistance and prevent flashover.
5.Maintenance-Free - Fully sealed and embedded, eliminating on-site servicing needs.
