Product Description

JDZ9-35 series of indoor voltage transformer, which is the epoxy resin casting, fully enclosed post structure. It's rated frequency 50Hz or 60Hz, rated voltage of power system up to 35kV(40.5kV), for measuring current, electric energy and relay protection.
The iron core and windings of the voltage current are casting together. The types of JDZ9-35 arid JDZF9-35 are single-phase transformers connected between phases to phase. The JDZF9-35 has two secondary windings and it has a energy measuring from voltage monitoring and relay protecting separately, which is made of cold rolled silicon steel sheet. This voltage transformer conforms to IEC60044-2 and GB1207-2006 standard.

Technical parameters and structure dimensions

Product features and scope of use

This series of voltage transformers is of epoxy resin casting pillar type fully enclosed structure. The iron core and the winding are cast into one body, and there is a mounting plate at the bottom. JDZ9-35 is single-phase and connected to the opposite phase. That is, the energy measurement and voltage monitoring are separated. JDZX9-35 is single-phase, connected to the ground, the primary A terminal is connected to the phase line, and the N terminal is grounded. JDZXF9-35 has three secondary windings, that is, the energy measurement, voltage monitoring and relay protection are separated. . JDZX9-35G is a fully insulated structure, the primary A terminal is connected to the phase line, and the N terminal is grounded. JDZXF9-35G has three secondary windings, that is, energy measurement, voltage monitoring and relay protection are separated.
It is resistant to dirt and moisture, and is also suitable for use in tropical areas. The transformer does not require special maintenance, but only needs to remove the surface dirt regularly. Since the transformer is fully enclosed and cast insulation, it is small in size and light in weight, suitable for installation in any position and direction. . A terminal box is installed at the secondary outlet terminal. There are three outlet terminal holes on the box, and the secondary wires can be drawn from different directions. The wiring is convenient, safe and reliable, and can realize anti-theft measures.
