    JDCF series oil-immersed inductive voltage transformer

    product outline
    product parameters
    product manual

    Product Description:
    JDCF series voltage transformers use electromagnetic oil-paper insulation for outdoor use; it is a fully sealed product. It is used as a voltage, electric energy measurement and relay protective device.

     

     Environment:

          -60℃~+50℃

     

    Features:

    This product has a reliable design and low magnetic density, it can avoid ferro-resonance over-voltage, the secondary coil can separate measurement from protection; the measuring precision can be up to grade 0.2 to meet the different requirement of customers and the high precision measuring requirement required by power departments.

     

    This product uses a stainless steel expander; it is carried out advanced vacuum drying and vacuum oiling treatment technology, so it has small dielectric loss and low partial discharge, and can ensure that the operation of product is safe and reliable.


    Rated voltage: 35kV~220kV

    Rated frequency: 50/60 Hz

    Internal insulating medium: Oil-paper

    Insulator: Porcelain or polymer

    Altitude: ≤3000m, others on request

    Specific creepage distance: 31mm/kV, others on request
