KYN61-40.5 High Voltage Cabinet | IEC Certified 40.5kV Metal-Enclosed Switchgear from China Suppliers and Factory
Model meaning
Conditions of use
- Altitude: ≤1000m;
- Ambient temperature: upper limit of ambient air temperature +40℃, lower limit -15℃;
- Relative humidity: The daily average relative humidity shall not exceed 95%; monthly average relative humidity shall not exceed 90%;
- Seismic intensity: The seismic intensity does not exceed 8 degrees;
- It's not suitable for places with obvious pollution such as corrosive or flammable gas and water vapor, etc.
- When the above normal service conditions are not met, the user can negotiate with the manufacturer.
Product characteristics
- The switchgear is designed with complete metal armor and fully enclosed structure.
- The interior of the switchgear is divided into four independent compartments: circuit breaker room, busbar room, cable room and relay instrument room. Each functional unit is sealed with metal plates and equipped with independent pressure release channel and release door.
- The switch cabinet body is made of high-quality cold-rolled steel plate processed by CNC sheet metal forming, and connected by high-strength bolts, nuts and rivet nuts. The surface of the components is sprayed or galvanized; it can be equipped with ZN85A vacuum circuit breaker and French Schneider's SF1, SF2 type and Alstom FP series SF6 circuit breaker to meet the needs of different users.
- The switchgear can perform circuit breaker opening and closing, moving-in/out, and ground switch opening and closing with the cabinet door closed.
- The switchgear is designed to prevent misoperation of circuit breaker, prevent pushing trolley with load, prevent ground switch from transmitting power at the grounding position, and prevent accidental entry into live compartments, meeting the "five prevention" functions.
- The convenient door panel observation window of the switchgear allows for viewing of the circuit breaker's on/off status, trolley position, energy storage position, and ground switch's on/off status.
- The switchgear trolley has good interchangeability, and the secondary wires are located in spacious cable tray, which are beautiful and easy to find. The primary cable connection is convenient.
- The protection level of the outer shell is IP4X, while the protection level is IP2X between small rooms and when the circuit breaker door is open. The installation and maintenance of the cabinet can be carried out on the front or back. The switchgear can not only be installed in a face-to-face or back-to-back double row arrangement, but also can be installed against the wall according to specific project requirements, which saves floor space and improves the safety and flexibility of the switchgear.

Frequently Asked Questions (FAQ)
1. What are the standard environmental conditions for using this switchgear?
The switchgear is designed for altitudes ≤1000m, ambient temperatures between -15℃ and +40℃, and daily relative humidity under 95% (monthly under 90%). The seismic intensity should not exceed 8 degrees, and the site must be free from corrosive or flammable gases and water vapor.
2. Which circuit breaker models are compatible with this switch cabinet?
It can be equipped with ZN85A vacuum circuit breakers, French Schneider's SF1 and SF2 types, and Alstom FP series SF6 circuit breakers to meet varying application requirements.
3. How does the switchgear prevent operational errors?
The switchgear features a reliable "five prevention" interlock system. This prevents misoperation of the circuit breaker, moving the trolley under load, operating the ground switch in a live state, and accidental entry into live compartments.
4. What is the IP protection level of the enclosure?
The outer enclosure provides an IP4X protection level. When the circuit breaker door is open or between internal compartments, the protection level is IP2X.
5. Can this switchgear be installed against a wall?
Yes, it supports flexible installation. It can be installed face-to-face, back-to-back, or directly against a wall to save floor space, depending on specific project needs.
