Domestic advanced: KYN79-12 / 1250-31.5 (i-AX) switching equipment for the fully assembled metal closed switch equipment, can meet the GB3906, DL404, IEC - 298 and other standards.

Cabinet to achieve complete assembly: the use of aluminum alloy profile frame and tibnor component assembly and, high assembly precision, good strength, beautiful appearance. Suitable in field and cabinets and cabinet has than similar types of other series switch device has the advantages of small volume, light weight, and other advantages.

Aluminum alloy profile frame: it has the advantages of small size, light weight, high positioning accuracy, anti corrosion effect, eliminating eddy current heating and so on.

Typical external dimensions: cabinet width (650) X cabinet high (2100) X cabinet deep (1400), cabinet width (650) X cabinet high (2365) X cabinet deep (1500).

Pure air insulation: first 650mm wide cabinet is interphase, the phase of the air net distance to reach 125mm, to meet the DL/T404 standard requirements.

Easy operation and maintenance: the instrument room is a high degree of 1300mm. man-machine interface at a glance.

Hand car interchangeable excellent: the operation of the unit effort. The product to ensure that all the same specifications of the car can be flexible exchange.

Simple and reliable lock: to achieve the "five anti" function, to ensure the safety of users.

Cable compartment space is abundant: cable chamber is provided with a plurality of single core (core) cable. Cable lapping height is more than 720, zero sequence current transformer, installed on the cable compartment.

Good protection: this type of switch cabinet use or combination of a single cabinet, the switch cabinet before, after the left and right are closed, the person and cabinet charged body completely isolated, cabinet top, the bottom of the cabinet with a closed, shell protection class IP4X.

Grounded and reliable: the grounding switch with short circuit closing capacity, the state can be carried out under the power cable terminal manual inspection, aluminum alloy frame shell grounding resistance is less than 150 mu.

Fitness wide: the selection of the EVH1 (ZN126) - 12 / 31.5 - 1250 - vacuum circuit breaker developed by our factory can also be matched with ZN63A-12 (VS1) and imported VM1 and VD4 circuit breakers.

Optional current, voltage sensor instead of traditional current, voltage transformer.

The optional GWZ-12 type contactor temperature monitoring device.
