Product Description
Description of ZW32-12 (G)
type outdoor high voltage vacuum circuit breaker
high voltage electrical equipment
ZW32-12 (G)-type outdoor high voltage vacuum circuit breaker for AC 50HZ, voltage 10 ~ 12KV three-phas power system, as breaking, Closing load current use, it has overload and short circuit protection function, to meet the control and measurement requirements, also allows remote control and monitoring. For protect and control the distribution systems of substation and industrial and mining enterprises and for the frequent use places of the rural power grid.
Use of environmental conditions:
o Ambient temperature: -40 to +40°C
o Altitude: ≤2000m
o Earthquake intensity: ≤8
o Environment humidity: month average relative humidity ≤90%, daily average relative humidity ≤95%
o Wind pressure: ≤700Pa (equivalent to wind speed 34m/s)
o No fire, explosion, serious filthy, chemical corrosion and violent vibration of places
o Customers have other special requirements, can be in order to put forward, our company can offer most satisfied
Features:
o Equipped with vacuum arcing chamber of the column in vacuum circuit breaker (performance is stable and reliable, and has no combustion and explosion danger, safety, free of maintenance, small volume, light weight and long service life
o Circuit breaker using permanent magnet operation system, the structure is simple, less parts, moving parts, only one, and the traditional spring institutions than nearly parts, greatly reduce the fault source, greatly enhancing the reliability
o Cancelled and prone to failure of mechanical off and lock device, make the whole system operation reliability greatly improved
o Permanent magnetic actuator controller unique adaptive and self-check function, may to the of the pma optimization, make vacuum circuit breaker of mechanical properties to achieve the best, extending a permanent magnetic actuator and vacuum arcing chamber of life
o Product the permanent magnetic actuator hold still, reliable and fast with the unique advantages, its inherent action time can't more than 10 ms and the action time consistent, very convenient at all levels in the circuit breaker protection parameter setting and action
o Product of permanent magnet operation system has electric points off and loading manual USD (national patent) and emergency break-brake four functions
o Installed have three-phase protection CT, zero sequence voltage CT, AB alternate with, through the controller of the real-time monitoring upload inputs, and with the value is used in the comparison to determine the type of line fault, and the corresponding processing;
o Operator seal in the switch internal, can avoid effectively switch from long outdoors environment and cause institutions rust
o Operator novel, simple, reliable operation, small volume, mechanical life can reach 30,000 times

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.
