24KV high voltage circuit breaker with good price
ZW32-24 type of outdoor high voltage ac vacuum circuit breaker is three-phase ac frequency 50 Hz, the rated voltage is 24kV outdoor switch equipment, applicable to all kinds of different nature of the opening load and frequent operation situation, apply to city nets, rural, mining and power equipment such as railway construction and renovation.
Compared with the international similar products ,our product has miniaturization, free of maintenance, intelligent etc. Characteristics. At the same time this product to the surrounding environment free from contamination, is the green environmental protection products.
1,Environmental temperature: no high than 40℃, no less than -40℃.
2,Air relative humidity: day average no greater than 95%, on average less than 90%.
3,The altitude does not exceed 2000m.
4,Wind pressure not more than 700Pa(equivalent to wind speed 34m/s)
5,Seismic intensity not more than eight level.
6,No fire, explosion, serious filthy, chemical corrosion and violent vibration of places.
7,If the customers have other special requirements, can be in order to put forward , our company can offer most satisfied.ne.
8,Circuit breaker three-phase pillar type structure, with open circuit performance is stable and reliable, and has no combustion and explosion danger, safety, free of maintenance, small volume, light weight and long service life etc;
9,Circuit breaker using fully closed structure, the shell adopts the high quality stainless materials. Has the sealing, prevent condensation sex, anticorrosive, prevent salt mist sex of environment such as excellent performance;
10,Insulation of the epoxy resin and silicone rubber compound insulation materials, insulation class is high, the filthy ability, good resistance to uv radiation, ozone, hydrophobic and higher resistance to high temperature ability. The cabinet without transformer oil, no six fluoride sulfur gases, meet the transformation and no oil green product requirements.
11,Operator for spring operation mechanism, manual and electric two, when need can add remote control device and avoid close brake current device. The requirements of the power supply source power is not more than 30W , easy to equipped with backup power supply. Unique design of the buffer device, excellent performance, the rally is small, low noise.
12,Vacuum arcing chamber adopts special stainless steel brazing techniques, do not need to electroplating, welding quality, stable and reliable, and a flat rate is low. Production process using metallization process to ensure that the products of air tightness, tensile strength greater than 130 Mpa, completely a seal platoon.
13,Current transformer is by current transfer switch than switch and is convenient for the user to in the installation, according to the actual size adjustment load current transformer of change than, achieve precise current protection.
14,Circuit breaker in the counter have action and is convenient for the user to maintain control products in the actual operation of The Times, make the maintenance staff to understand the product real date.
15,According to the requirements of the customers, and the corresponding controller with automatic coincidence, stage is a device, which is the ideal equipment of automation distribution network.
