Potential transformer is an epoxy resin fully enclosed castable insulated indoor product, suitable for all kinds of high voltage switchgear, rated frequency of 50Hz, rated voltage of 10kV (or 6kV) and below power system for voltage, electric energy measurement and relay protection. This product is single-phase double-coil fully enclosed structure. The iron core is wound into a ring by cold rolled silicon steel sheet. The primary and secondary windings are wound on the iron core. The secondary outlet wire is provided with a wiring shield, and the outlet groove is provided on the shield. The product has good resistance to pollution and moisture
General:
The voltage transformer is a completely closed structure of epoxy resin casting, the insulating medium is epoxy quality, the iron core and coil are fixed in the transformer by epoxy resin casting. The voltage level is generally 35kV and below, and a few 66kV are also available. Suitable for rated frequency 50Hz or 60Hz, rated voltage 35kV power system, for electric energy measurement, voltage monitoring and relay protection. This product conforms to IEC60044-2 and GB1207 "voltage transformer" standards.
Key Feature
This type of voltage transformer has a pillar structure and is fully enclosed and cast with epoxy resin.
It is resistant to pollution and humidity, and is also suitable for use in tropical areas. The transformer does not need special maintenance, and only needs to remove surface dirt regularly. Because the transformer is fully enclosed and castable, it is small in size, light in weight, and suitable for installation in any position and direction.
The terminal box is installed at the secondary outlet terminal, and there are three terminal holes on the box, which can lead the secondary wire from different directions, and the wiring is convenient, safe and reliable, and can realize the measures to prevent electric theft.
