The voltage transformer adopts epoxy resin casting fully-enclosed insulated structure. It is used for voltage, power measurement and relay protection in line and for the equipment with rated frequency 50Hz, rated voltage 10-12 kV or below.
The best characteristic of the transformer is that primary terminals are added fuses, so the security of the transformer is improved. If it is fixed in a switch cupboard, it need not equip with another fuse, and can save a great huge space, so the cost of switch cupboard may lower. And that fuse's replacing is very convenient, so as screwing off primary terminal screw cap and fixd fuse into it and again screwing on. The transformer may absolutely supersede type JJDZ-11 voltage transformer, and it is a perfect renewal\replacing product.
