JDZ9-35Q voltage transformer
JDZ9-35Q voltage transformer adopts single-phase and double-winding casted by epoxy resin and is designed to measure electronic energy and relay protection in electronic system at 50Hz current.
product description :
JDZ9-35Q voltage 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.
For insulation and protection, components are cast in hydrophobic cycloaliphatic epoxy resin (HCEP) using automated vacuum pressure. HCEP materials provide superior arc trajectory, ozone and UV resistance while maintaining physical strength. The hydrophobic surface properties of HCEP ensure highly reliable performance in wet, humid or contaminated environments.
Can be used for 35KV distribution lines, coal mines, power plants, railways, factories… Strictly comply with IEC60044-2; IEC 61869-1,3; ANSI/IEEE C57.13.
