Product Overview
JDZV8-12R voltage transformer, epoxy resin casting and full enclosed construction, is used indoor for measuring current, electric energy and protective relaying in single-phase or three-phase AC circuit with the frequency 50Hz or 60Hz and highest voltage for equipment 12kV.
The product has the feature of high reliability, low magnetism of core, large creep distance of external insulation and maintenance free etc.
Key Features
Compact and Lightweight Design：With a highly compact structure, its volume is reduced by 40% and weight by 50% compared to similar products. This enables easy installation in space-constrained scenarios like switchgear and ring main units, saving both equipment layout space and installation costs.
High Insulation Strength and Safety：The epoxy resin insulation system withstands 12kV rated voltage and 75kV lightning impulse voltage, with partial discharge ≤10pC. It effectively prevents phase-to-phase short circuits and ground breakdown. The built-in overvoltage protection fuse quickly cuts off the circuit during faults, ensuring system safety.
Wide Temperature Range Adaptability：Operating within -40℃ to +70℃, it suits extremely cold or high-temperature regions. The epoxy resin material features excellent thermal stability, eliminating long-term aging or cracking risks, with a service life exceeding 30 years.
