KYH1-40.5 model Metalclad Centered Metal-enclosed Switchgear (hereinafter referred to as switchgear) is a new product.

The product has the outstanding advantages as follows:
1.1 The enclosure is completely formed by Al-Zn coated steel plate after multiple bending processed by CNC machine,then is asse mbled with the bolts, which has strong mechanical strength and effectively ensure the neatness and good appearance. The door is painted by the plastic powder and has strong anti-impact and corrosion proof ability. The protection grade of enclosure is IP4X.
1.2 The main circuit breaker is VHY1-40.5 model Solid-sealed Vacuum Circuit Breaker. It has the unique advantages of long life, high reliability, less maintenance and small volume,furthermore, it has perfect and reliable anti-misoperation function. Of course, the switchgear can be equipped with other similar circuit breakers.
1.3 The circuit breaker handcart is centred structure, which inherits the advantage of KYN28 model switchgear. This structure avoids the adverse effects for the installation foundation against the movable/fixed contacts, and is convenient for maintenance and overhaul.

NORMAL SERVICE CONDITIONS
Environmental ambient temperature: +40 -15 , daily average not exceed 35 ;
Altitude above sea level: not exceed 1000m;
Relative humidity: daily average less than 95%, monthly average less than 90%;
-3 -3 Saturated vapor pressure: daily average less than 2.2 10 MPa, monthly average less than 1.8 10 MPa ;
Earthquake intensity: not exceed 8 grade;
The environmental air without flammable, explosive and corrosive material;
Site without frequent vibration.

If the service conditions exceed the above mentioned range, the user shall consult the manufacturer.
The switchgear shall be equipped with a heater to avoid the condensation. The heater shall operate all day when the switchgear is in the steady or operating state.
For the special locations of bad operation conditi ons, e.g . the underground substation, the unmanned substation and son on, the constant temperature & humidity-reduced equipment shall be added indoor to improve the o perating condition and ensure the safe and reliable operation of the switchgear.
