New type medium voltage contactor for frequently turn on and off
JCZ8-12 Indoor vacuum contactor 12KV (fixed)
The main function of the high-pressure vacuum contactor is to operate the large load current frequently, especially suitable for harsh environment and flammable and explosive dangerous places.
Introduction to GN30-12 Disconnector
GN30-12 Rotary Disconnector (Isolating Switch)
The GN30-12 is a common type of high-voltage, indoor, rotary-type disconnector (isolating switch). It is primarily designed for use in 12kV AC three-phase power distribution systems.
AC high-voltage SF6 circuit breaker LW36-40.5 2000-31.5 40.5KV
LW25-252/4000-50 self-energy AC high-voltage SF6 circuit breaker is an outdoor product, which is suitable for 50Hz AC power grid with altitude not exceeding 2000 meters, ambient temperature not lower than 30℃, maximum voltage 252kV and pollution level not higher than IV. Used to cut off rated current, fault current or switch lines to achieve control and protection of the power system can also be used as wire cutters.
This product uses SF6 gas as the arc extinguishing insulating medium, adopts the world's most advanced self-energy arc extinguishing technology, and is equipped with a new spring operating mechanism, long electrical life, low running power, low noise, high reliability, simple structure, small volume, long maintenance cycle. In the current process of power equipment towards oil-free and large capacity, it can completely replace the same type of imported products.
What are the main functions and roles of the GW5-40.5Kv Outdoor disconnector (isolate switch)?
The GW5-40.5kV disconnector is a critical safety and isolation device in high-voltage electrical systems, ensuring that work can be performed safely and that the grid can be operated flexibly.
What is the vacuum contactor?and what is the difference between vacumm circuit breaker & vacuum contactor?

SM11 10/0.4KV Oil immersed
Power transformer
Description
Iron core:
the iron core is made by crystal grain-oriented silicon-steel sheet;GEORG cross cut shear(made in West
Germany)is adopted to cut the silicon-steel sheet with a 45°joint seam;fold the sheet into a multistage roll
cross-section to reduce the noise and power consumption.
Coil:
cylinder type for high voltage; cylinder type or foil type for low voltage; this can increase the ability to resist
short circuit and strike; and the distribution of magnetic path is more rational.
Oil tank:
the oil tank is made by fine cold-rolled steel sheets; GEORG corrugation oil tank production-line is adopted;
to meet environmental needs, then, antiseptic coating material is applied on the surface, which can meet the
requirements for petroleum and chemical industry(much oil stain and many chemical substances).In addition,
the corrugations not any possess heat radiation function, but also meet the requirement for oil expansion and
oil contraction trader normal performance, The isolation from air guarantees a low aging speed of oil and a
long life expectancy of transformer.
