Product Description
LVQB(T) SF6 Current Transformer
SF6 Gas-Insulated Voltage Transformer (abbreviated as SF6-GVT) is a type of voltage transformer that uses sulfur hexafluoride (SF6) gas as the insulation and arc-extinguishing medium. It is mainly used for voltage transformation, electric energy metering, and relay protection in power systems. Widely applied in high-voltage/ultra-high voltage substations and GIS (Gas-Insulated Switchgear) integrated devices, it features a compact structure, excellent insulation performance, and strong adaptability to harsh environments.

Outdoor High-voltage Electric Metering Box
An outdoor high-voltage electric metering box is a special complete set of equipment installed in outdoor high-voltage power distribution systems to measure the power consumption of high-voltage lines. It integrates core components such as current transformers, voltage transformers, and metering meters, and has the functions of metering, protection, and monitoring.
Excellent protection performance: Adopts a sealed, waterproof, dustproof and corrosion-resistant structural design to adapt to harsh outdoor environments such as high temperature, rain, snow and sand dust, with a protection grade usually reaching IP54 or above.
