JSZV8-12R Three-phase Voltage Transformer

Product Overview

JSZV8-12R Three-phase Voltage Transformer 12kV Indoor Three-Phase Epoxy Resin Type.The voltage transformer (with inbuilt fuses) , epoxy resin casting and fully enclosed construction, is used indoor for measuring voltage,electric energy and protective relaying in the electric system 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 creepage distance of external insulation and maintenance free etc.

Feature

• Three-phase Precise Metering: Specifically designed for 12kV three-phase systems, featuring high-permeability cores and symmetric winding structures. With a metering accuracy of class 0.2, it ensures balanced and stable three-phase voltage conversion, guaranteeing precise and consistent metering and monitoring data for three-phase circuits.

• Enhanced Environmental Adaptability: Adopting fully enclosed epoxy casting technology, the core and windings are tightly encapsulated, effectively resisting dust and moisture. It operates stably in industrial environments with temperatures ranging from -25℃ to 40℃ and humidity ≤95%, suitable for enclosed scenarios such as switch cabinets.

• Highly Reliable Insulation Performance: Boasting excellent insulation strength, it can withstand 12kV rated voltage and operational overvoltage impacts. With partial discharge ≤10pC and strong anti-corona performance, it reduces the risk of insulation aging and ensures long-term safe operation.

• Compact Integrated Design: Optimized in volume, it supports three-phase integrated installation, adapting to narrow spaces. The standardized installation dimensions are compatible with multiple fixing methods (e.g., cabinet embedding, bracket mounting), reducing installation footprint.

• Convenient Operation & Maintenance Features: Offering flexible outlet options (cable/busbar connection), daily maintenance requires no complex debugging. It has good anti-electromagnetic interference capability, adapting to the needs of rapid deployment and long-term stable operation, thus reducing maintenance costs.
