JDZ20-10Q single-phase semi enclosed fully insulated cast voltage transformer is an epoxy resin cast semi enclosed product used as an operating power supply and voltage measurement for outdoor vacuum circuit breaker ZW8 with a rated frequency of 50Hz and a rated voltage of 10kV and below.

Structural characteristics:
This type of transformer is a semi enclosed fully insulated product made of epoxy resin. The iron core is made of laminated cold-rolled silicon steel sheets with high quality. The insulation of the transformer is composed of epoxy resin, which is small in size and lightweight, and only takes up limited space for installation. All windings are completely cast in epoxy resin, which has excellent insulation performance, resistance to impact and mechanical pressure, and can protect the windings from moisture. The primary winding leads out terminal AB; the secondary winding leads out terminal A and B are clearly marked on the casting body. The primary winding outgoing line is led out by silicone rubber insulated flexible wire, which has high insulation strength and easy wiring.
