Product Range

YULE Vaccuum Circuit Breker Panel

Features & Safety

Fully type tested and conforms to IEC 60298/IS

Suitable for capacitor switching & auto reclosing duty

HV & LV compartments are fully segregated


Minimum operating linkages, noise and operating impact ensure low dynamic loading

Because of no fire hazards, breakers are suitable for use in Oil Refineries, Petrochemical complex, cement, paper industry

VCB is restrike free and hence it is ideal for Capacitor Switching duty.

YULE Outdoor Porcelain Clad Vaccuum Circuit Breker

PCVCB is structure mounted easy to install vacuum switchgear for use in 12/ 36 kV system It is a porcelain clad construction like to conventional outdoor high voltage switchgear and is a Gang operated triple pole circuit breaker fitted with reliable and proven vacuum interrupters.

Dry Type Transformer ( UPTO 11KV, 1.6 MVA)

Dry Type Transformers have been manufacturing nearly 20 years are mainly were Class C & H insulated with polyester / silicon varnish impregnation.

Range 100 KVA upto 1600 KVA with a system voltage 12 kV maximum.

Advantages No Fire Risk, Lighter in weight, Efficient noiseless operation, No soak pit for oil.
