Instrument Transformer

LVB series of oil-immersed inverted-type current transformer for the inverted fully enclosed structure. Mainly by the expander, oil conservator, winding, body, porcelain sets, base, and junction box and other components.

Three pole operation,50Hz, outdoor pole mounted vacuum circuit breaker is designed for pole-mounted or substation applications up to 12kV,630A,25 kA. These pole mounted vacuum circuit breakers are used for control and protection of overhead distribution lines, cables, transformers,motors, generators,and etc.They are able to be operated at ambient temperatures from -40℃~+40℃.They are also flexible to receive various relays and voltage inputs besides a wide auxiliary and control voltage range -24V,48V,110V,220V.Currently,spring mechanism and permanent magnetic mechanism are available upon user needs.

The high insulation capacitive voltage transformer operating environment a wide range of temperature range -45℃~+55 ℃, the highest elevation to meet the 5000m, the maximum wind speed 150km/h, the maximum seismic intensity of 9 degrees.

LB series of oil immersed vertical current transformers are the vertical and fully closed structure, mainly by the expander, a terminal, porcelain sets, primary winding, secondary winding, fuel tank and other parts, the lower part of the oil immersed current transformer with grounding plate for products Ground, with a drain valve for oil samples.

LVQB series SF6 current transformer is an inverted fully closed structure, mainly by a terminal, shell, casing, inflation valve, density controller, junction box, base and other components.

SF6 voltage transformer fully enclosed structure, mainly by a high-voltage wiring board, high-voltage insulation casing, box, body and outlet box composed of five parts.
