GFJZFW-24W324KV MULTI WINDINGS HIGH ACCURACY OUTDOOR POTENTIAL TRANSFORMER

GFJZFW-24W3 24KV high accuracy 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. Applied for outdoor service; suitable for operating meters, instruments, relays and control devices.
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 hydrophobic cycloaliphatic 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 24KV distribution line, Coal mine,power plant,Rail way, factories.. . Strictly Comply IEC60044-2; IEC 61869-1,3; ANSI/IEEE C57.13.
