Overview
SF6-insulated ring main unit and SF6-insulated compact switchgear are used in medium voltage distribution networks. They offer a sealed stainless steel tank which contains all the live components and switching functions. The transformer is protected either by a switch fuse combination or a vacuum circuit breaker.
SF6-insulated ring main unit can be supplied as a 2, 3 or 4-way unit in standard configurations with additional equipment according to customer specification.
SF6-insulated compact switchgear has a unique flexibility due to its extendibility and the possible combination of fully modular and semi-modular configurations, with a maximum of 5 modules in one SF6-tank.
The units are delivered from the factory ready for installation. Routine tests are carried out on all units/ modules before dispatch. No special tools are required for installing the equipment.

About Us
Founded in 1996, with a registered capital of 10 million USD, Zhejiang Farady Electric enjoys about 20 years' experience in MV transmission and distribution electrical equipment manufacture.We are National Hi-tech enterprise, National Spark plan Program,State Hi-tech enterprise, State Innovation R&D center, Patent demonstrate company.
Farady is located in Liushi of Yueqing, Zhejiang,China,main products include: Transformer/RMU/switchgear/AVR/ACR and MV indoor and outdoor switch. All the products of ours have passed the national and international laboratory type test, Farady Electric was qualified supplier of China State Grid and China southern Grid.
With ISO9001/14001/18001, we are strike for create value for our partner and customer.
There is more than 20 distributors and agents worldwide already trust us and distribute Farady product there, we are not only export product, but also provide whole technology solution to help partner to establish local factory in our business line.
Today, boasting the value of products specialization, brand management, and business globalization, with the sprits of pragmatism, innovation, efficiency, and responsibility, Farady Company is dedicated to become the top name in the international business from china, and contributes its share to the transformation from the Made in China into the Invented in China.
Our Advantages
(1). Energy conservation: Farady voltage regulating type capacitors will change the output reactive power by regulating voltage on capacitors, so that the reactive power can be adjusted smoothly. Comparing with other method, it can ensure the capacitors in best condition, the energy saving effect is much better(2). Low cost:If the old power transformer substation need to reform, only need to add a voltage regulator between the circuit breaker and capacitors, the original circuit breakers, reactors, capacitors can be reuse, greatly reduce the cost of transformation
(3). Maintance Free:When traditional circuit breaker and contactor switching, switching devices and capacitors often damaged because of the above problems, result in high maintenance costs, using Farady devices, automatic control reactive power output, there is no potential risks of other equipments, greatly reducing maintenance and staff costs in power transformer substation
(4) Quality Assurances
