GFJDZW-20 GFJDZXW-20G20KV DOUBLE & SINGLE POLE OUTDOOR SINGLE PHASE VOLTAGE TRANSFORMER

JDZW-20 and JDZXW-20G 20KV High Accuracy Outdoor Voltage transformers are designed for outdoor metering and relaying applications. This product has the characteristics of high precision 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 medial voltage AIS, or can be used for medial voltage switchgears. They can operate in all kinds of environments (such as wide range temperature (-50~70℃), high altitude, high humidity, high pollution or salt). This model JDZW-20 JDZXW-20G outdoor voltage transformer is also as voltage source to supply 220V voltage. Strictly Comply IEC60044-2; IEC 61869-1,3; ANSI/IEEE C57.13.
