FZW28 Outdoor Vacuum Load Break Switch

General:
Fzw28-12 is a kinds of outdoor vacuum power distribution equipments of rates voltage 12KV and power system of AC 50HZ.opening and closing load current and closing current.
It is used for protecting and controlling distribution systems in transformer substations and industrial and mining enterprises.especialy for upgrade rural and city power grids.
There are many kinds of operation control switch in overhead line distribution system.FZW28-12 column vacuum load switch: no oil,simple mechanism,reliable performance,no need maintain and so on.this product match with FDR fault detector and RTU remote control terminal device into simple power distribution automation system,It can achieve the automatic positioning of overhead lines and failure of the automatic isolation of the fault.?

Features:

Excellent breaking performance: import Japan technology , To carry out expansion design,The closing current is expanded to 20 KA. Use vacuum arc-extinguishing chamber and SF6 gas to resistance. The switch has a fault in series with the vacuum interrupter. Arc performance and pressure resistance is superior. Between the two by the mechanism to ensure the order of fracture(The vacuum interrupter is opened than closed)Fit for break load current. In addition to vacuum break inside the switch. There is also a SF6 isolate break with high pressure resistance.

High security: Both the arc and the insulating medium are oil-free.There is a explosion-proof equipment installed on the top of the cabinet. Even though the internal fault happen. There is no high temperature gas and splash leaked.

Maintenance-free: Main loop of the witch and operating mechanism Sealed in the cabinet of SF6 medium.Main loop of switch leap out with cable head or Corner Sleeve.?

Because use zero Zero gauge SF6 gas insulation That makes switch volume delicate and compact. While avoiding leakage of hidden dangers. With manual and automatic operation makes switch flexible operation. Use electromagnetic operating mechanism that keep closing and opening gate with electric energy. There is an electrical switch is closing and no electrical switch is opening. Structure is simple and reliable.

Flexible installation: It could used Post hoisting or sitting installation.

With automated power distribution interface:Can be equipped with a variety of variable current transformer that use for measuring, protecting and equipped with motion assist.

High reliability: Our company have a perfect quality management system makes produce have high reliability. The SF6 gas inflation pressure is zero gauge that not easy to leak. Reliable sealing technology that ensure 20 years normal work or SF6 gas.

No need to check Maintenance: Electric parts and operating mechanism are inside the sealer and not affected by external environment. The arc is sealed in the vacuum interrupter. No pollution inside the switch so the switch don't need to maintenance.
