JDZ-3、6、10 indoor Voltage Transformer

Description and meaning of model

JDZ-3, 6, 10 indoor Voltage Transformer is a commonly used device in power systems, mainly used for voltage measurement, protection and monitoring. It is suitable for indoor power systems with rated voltages of 3kV, 6kV and 10kV, and can accurately convert high voltage into low voltage signals for use in measuring instruments, relay protection devices and automatic control systems. It has excellent insulation performance and anti-interference ability, and can operate stably in harsh power environments.

Characteristic of structure

JDZ-3,6,10 type voltage transformer is epoxy resin casted of semi-closed structure. The core adopts high grade cold rolled silicon-steel sheet.With small size, light weight, small space for installation, all windings are completely casted in the epoxy resin. excellent insulation, anti-impulse and resist mechanism pressure Keep windings without moisture. The down-lead terminal signs of the primary windings are A, B; the down-lead terminal signs of the secondary windings are a, b; these signs are clearly marked on the surface of the product.

Beside the earthing signs,the earthing bolts is used for earthing. The whole structure is compact and it is convenient for use.
