Product features

environmental protection

All the materials used in product manufacture are innocuous and harmless material, and no toxic and harmful substances will be discharged in the use. The materials can be recycled after the life cycle, which determines the environmental protection of the use.

All insulation fully shielded epoxy resin switch cabinet closed, fuse cabinet (epoxy resin has excellent electrical properties, mechanical properties, thermal characteristics, very early for electrical equipment, achieved good performance. " The switch is simplified, and the fuse is simplified by epoxy resin APG process. Insulation is the key component of group insulation switch. It is both insulation and bearing parts. It is also required to meet the technical requirements of heat resistance, weather resistance, cracking resistance, high mechanical strength and good insulation strength. The volume of the simplified body is large, with many inserts and different shapes. Shen Mei Electric has many years of experience in the design and manufacture of insulation, from the design of the cylinder, the material formula, the process flow to ensure the quality of the mass production of the components.  According to the user's request, we can provide an external shielding grounding touch cylinder.

Wide range of use

The switch simple and isolation switch operating mechanism box adopts the static and static sealing structure to form the sealed cavity, which is filled with zero surface pressure and dry nitrogen, and does not use SF6 gas. It is completely isolated from the external environment. All working conditions of the switchgear are guaranteed.

Easy to install and transport

The single cabinet structure, the whole series of product unified design, provide a variety of cabinet type (circuit breaker, load switch cabinet, load switch "fuse combination electrical cabinet, metering cabinet, PT cabinet, bus cabinet, mother cabinet, etc.), and the geometric dimensions of the shape are completely consistent. Adopt general insulated busbar produced by professional cable accessories manufacturer, cable plug head. The switchgear can be assembled on site and expanded at will, avoiding the inconvenience of transportation and installation. A combination cabinet can also be provided if the user is required.

Maintenance free

In the solid insulation indoor AC high voltage vacuum switch cabinet, the high voltage switch parts of the operating mechanism are in the full seal state, so that the cleaning and maintenance can be avoided, and the cost of operation and maintenance can be reduced.

Safety

Because of the shielding measures adopted in the touchable part, the occurrence of human body electric shock accidents is eliminated, and the safety use is improved. The perfect interlocking and interlocking system can clearly see the three phase isolation fracture and avoid misoperation accidents. The application of SF6 gas has been abolished completely, and the explosion accident caused by the decrease of gas pressure and insulation performance and arc extinguishing ability of SF6 ring net cabinet has been avoided. The interphase isolation structure is strengthened to avoid expanding or triggering explosion accidents by interphase or multi circuit short circuit. A vacuum interrupter with explosion-proof performance is adopted, and the switch sleeve is provided with a switch.

Further protection performance. The auxiliary grounding switch of the load switch fuse combiner is sealed by the vacuum switch tube in the fuse key barrel.

Ease of operation

The isolation switch grounding switch has only one operating handle, without identification and fear of error. When the circuit breaker runs, the operating handle of the isolation switch grounding switch can not operate. The operation procedure is clear, as long as the personnel with the knowledge of the electrician will operate, and the complex technical training is disordered. In this way, the operation becomes very simple and the operation error is eliminated.

Intelligentization

The switch cabinet has intelligent interface and sensor installation position, and the intelligent equipment can meet the requirements of smart grid after installation of intelligent equipment.

Diversified operating mechanism

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