GFJDZX0946-3533KV SINGLE POLE HV INDOOR INSTRUMENT POTENTIAL TRANSFORMER

GFJDZX0946-35 35KV HV indoor instrument potential transformer are designed for metering and protection applications. This product has the characteristics of high efficiency and large capacity, and can be customized according to customer requirements.
The primary and secondary coils are wound using special winding and shielding techniques for improved voltage stress distribution.Each coil is carefully insulated with mylar film to provide a high dielectric medium between layers. The completed winding structure and double-loop cores are assembled to a support frame.

DESCRIPTIONFor insulation and protection, the assembly is cast in hydrophobiccycloaliphatic epoxy (HCEP) using automatic vacuum pressure. The HCEP material offers superior arc track, ozone, and ultraviolet-resistive properties while maintaining physical strength. The hydrophobic surface properties of HCEP ensure highly reliable performance in wet, humid, or polluted environments.
It can be used for 35KV distribution line, Coal mine,power plant,Rail way, Factories.. . Strictly Comply IEC60044-2; IEC 61869-1,3; ANSI/IEEE C57.13.
