JLSZV-35, JLSZV-35W high-voltage dry power metering box is a three-phase two-component combined transformer, which is composed of two current transformer components and two fully insulated voltage transformer components assembled on a channel steel base. For outdoor 35kV power system for voltage and current energy metering. Two current transformer components are connected in series on the A and C phases of the line, and two voltage transformer components form a three-phase V-type wiring. The product is a composite insulation product of epoxy resin and silicone rubber, and the performance is stable. And the combined transformer is assembled with a set of 35kV three-phase combined lightning arrester (HY5WZ1-51/150*51/134), which effectively limits various overvoltages that may occur in the outdoor operating environment to protect the combined mutual inductance. Reliable operation of the device.

JLSZ□-35W is a combination of voltage and current transformers, and a combination of combined transformers and measuring instruments is called power metering box. The product is used on a three-phase system network with an outdoor rated frequency of 50 Hz. The primary voltage is 6, 10, 35 kV and the secondary voltage is 100V. The primary currents are: 1, 2, 3, 4, 5, 10, 15, 20, 25, 30, 40, 50, 75, 100, 150, 200, 250, 300, 400, 500, 600, 750, 800 , 1000A, the current is 5A. The metering box has high precision, light weight, reliable insulation, can prevent stealing and leakproof, and is an ideal equipment for current power management.

JLSZW-6, 10 three-phase outdoor dry high-voltage power metering box (combined transformer), consisting of two or three single-phase voltage transformers (PT) and current transformers (CT), PT.CT are electromagnetic . This transformer is suitable for three-phase AC with rated frequency of 50Hz and rated voltage of 6kV. It is used for electric energy measurement on iOkV power grid and installed on the high voltage side of power supply transformer. The instrument box is equipped with three-phase active energy meter and reactive energy meter. It is used to directly measure active and reactive electrical equipment in high-voltage lines.
