15 kv Metal Enclosed Switchgear advantage

> Leading technology
- Standard anti-corrosion and salt spray environmental plan to meet the stringent environmental requirements of the site
- Strong versatility, can be configured domestic and foreign brands of circuit breakers, domestic series (VS1), Schneider HVX series, ABB VD4 series and so on
- It has the functions of "five prevention" (IP2X IP4X) to prevent the misoperation of circuit breaker, to prevent the push-pull trolley with load, to prevent the grounding switch from being turned off while charged, to prevent the grounding switch from sending power at the grounding position and to prevent the accidental entry of the charged interval.

> Cabinet put oneself in another's position
- The whole is composed of 2-3mm aluminum and zinc plates by multiple bending
- Laser numerical control equipment cutting, drilling, bending, to ensure the processing accuracy
- The exterior is coated with electrostatic epoxy powder, which will not take off paint for 50 years

> Functional units
- Various types of microcomputer integrated relay protection devices can be installed on the panel of relay chamber of this product
- Through CAN bus control with communication interface, intelligent control of the system CAN be realized (remote control, telemetry, remote signaling and remote tuning functions).
- The cabinet body is divided into four separate compartments, and the protection class of the outer shell is IP4X. When the door of each compartment and circuit breaker chamber is opened, the protection class is IP2X
- Heaters can be installed according to user requirements to prevent condensation and corrosion;
- All operations are carried out under the closed state of the cabinet door, with high protection level, which can prevent the intrusion of sundries and pests

> Busbar system
- High quality three-phase tin bus copper bar, high mechanical strength, good heat dissipation

> Processing and assembly
- Dust-free workshop to ensure insulation
- Assembly workers should be on duty with at least 6 months training
- The secondary connection is automatic terminal crimping machine to ensure reliable connection
- The bolts are reinforced with power tools to ensure proper torque
- The copper bus is CNC cutting, punching and bending to ensure the accuracy
- All kinds of experimental tests before leaving the factory to ensure the normal operation of the equipment
