Product features
Environmental protection

All products use in the manufacture of materials is a harmless substance, using, also won't discharge any poisonous and harmful substances in the materials can be recycled after life cycle, determines the use of environmental protection.

All full sealed full shielding epoxy resin insulation switchgear, fuse cabinet put oneself in another's position (epoxy resin with excellent electrical properties, mechanical properties, thermal properties, long used for electrical equipment, achieved good results.

The switch body and fuse body are formed by epoxy resin APG process.

Insulation simple is the key component of group insulation switch.

It also meets the technical requirements of heat resistance, weather resistance, cracking resistance, high mechanical strength and good insulation strength.

It is very difficult to manufacture because of its large size, many embedded parts and various shapes.

Shenmei electric has many years of experience in designing and manufacturing insulation parts, and has made great efforts to ensure the quality batch production of this part from the aspects of cylinder design, material formula and process flow.

According to the user's request, the outer shield grounding can be provided to touch the cylinder body.

Wide range of application

The switch body is simplified and the isolating switch operating mechanism box is formed into the sealing cavity by using the static and static sealing structure. It is completely isolated from the external environment with no SF6 gas and no pressure inside.

Ensure the full operation of the switchgear.

Convenient installation and transportation

Monomer tank structure, unified whole series of product design, provide the user needs a variety of tank type (ark of circuit breaker, load switch cabinets, load switch "fuse combination electrical cabinets, measuring tank, PT, bus, bus coupler cabinets, etc.), and geometry shape.

Adopt professional cable accessories manufacturers to produce universal insulated bus, cable plug and plug.

The switchgear can be assembled on site and expanded at will, avoiding the inconvenience of transportation and installation caused by multiple sets of combiners.

We can also provide the composite cabinet if required.

Free maintenance

Metal-enclosed solid insulation vacuum switchgear in addition to the operating mechanism of high voltage switch place was in a state of fully sealed, so that you can do it from cleaning and maintenance, reduce the cost of operating maintenance.

security

Due to the use of shielding measures on the touchable parts, the occurrence of personal electric shock accidents is prevented and the safety of use is improved.

Perfect interlock interlock system, three-phase isolated fracture is clearly visible, avoiding the occurrence of misoperation accident.

The application of SF6 gas was completely eliminated, and the explosion accident caused by the decrease of insulation performance and arc extinguishing capacity of SF6 ring cabinet due to insufficient gas pressure was avoided.

Strengthen phase - to - phase isolation structure, avoid phase - to - phase or multi - loop short circuit expansion or explosion accident.

The vacuum arc extinguishing chamber with explosion-proof property is adopted

Further protection performance.

The auxiliary grounding switch of the load switch-fuse combiner USES the vacuum switch tube to seal in the fuse key cylinder.

Operational ease

Isolating switch earthing switch is only an operating handle, without recognition and worry about mistakes, the operation of circuit breaker, disconnecting switch operation of earth switch handle cannot operate, operating procedures be clear at a glance, as long as a slight electrical knowledge staff will operate, complex technical training for the disorder.

This makes the operation extremely simple and prevents the operation error.

intelligent

The switch cabinet is equipped with intelligent interface and sensor installation position, and the intelligent equipment can meet the requirements of the smart power grid.

Multiple operating mechanism

Switch can be equipped with spring, permanent magnet two operating mechanisms, convenient for users to choose.
