Description of KYN28-24 switchgear

36kv circuit breaker VS1-12 series indoor high voltage vacuum circuit breaker, 3-phase ac rated voltage isolator, and indoor 12kV voltage switchgears.And KYN28-12 (Z) (GZS1), also can complete switchgear with various types of complete switchgear.Applicable to transmission power substation, etc, and the control and protection system, and can also be used to frequent operation.GB1984 products comply with the requirements of high voltage circuit breaker exchanges.Its products have: isolation and fuse handcart, etc.
Breaker using composite insulation, satisfy normal operation conditions and requirements of the insulation, effectively reduce the volume of the general layout, the circuit breaker, beautiful, concise.

Operator USES ontology of spring and the circuit breaker one-piece body and ac or dc operate, also operated by hand.Circuit breaker is divided into fixed and handcart type, including its special propulsion, but is easily switch in mobile handcart, auxiliary machinery atresia, meet compulsory cabinet "five-protetion" functional requirementsWide application range, which can be installed in stationary switch, can also be used to move off its complete switchgear.

The use of environmental conditions:

1.Ambient temperature: not higher than +40 °C, not less than -15°C

2. Altitude: not exceed 1000m.

3. Relative humidity: daily average of not more than 95%, month average of not more than 90%.

4. Earthquake intensity: not more than ten.

5. No fire, explosion hazard, serious filthy, chemical corrosion, as well as places of intense vibration.

General

VCBI (VS1)-12 Series High-voltage Breaker is a kind of indoor high-voltage switch equipment with 50/60HZ three-phase alternation current and 12KV rated voltage, which combined the technique of the ABB Corporation in Switzerland and domestic development state and manufacturing capability. The general framework of this product is taken the form combine the front body and operation system into one. Product complies with the standards BG1984, IEC62271-100.

Because it adopted the composite material, there is no pollution and explosion danger, the insulation level is high.

Our story with customers

In 2005,we received the email from ALIBABA that a Russian customer would like to order the KYN28-12 indoor metal-clad enclosed switcgear.We confirm the product parameters and pictures carefully again and again with the client,the last communication is the most difficult in price,it is a psychological warfare,customers began to demand a 20% cut,we insist on our price,emphasis on the various advantages of our products with the high quality. After compared with other factory,Russia customer finally chose to coperation with our company.After more than 20 days,customers sent a email to tell us that they are very satisified with the goods. At the same time,he praised our good service attitude,delivery on time,good quality,until now the Russia client has been our long-term customer,also is our good friend.
