SafeSwitch is an air insulated (AIS), metal enclosed, switchgear cubicle. It is suitable for electric distribution automation and compact also expandable metal close switchgear. It characters in its simple structure, flexible operation, reliable interlocking and convenient installation etc., which can provide the satisfactory technical projects both for different application occasions and users.

With the adoption of sensor technology and the protection relay up to date, plus the advanced technology and flexible assembly project, SafeSwitch can completely meet the requirement of continuously variable market.

SafeSwitch can take SF6 load break switch; also according to user's demand can be assembled with the vacuum circuit breaker. Operational methods  can be either manual or motor driven.

1 Load Switch : Load switch and earthing switch in an enclosure filled with SF6 and satisfying "sealed pressure system" requirements.

2 Busbars : all in the same horizontal plane, thus enabling later switchboard

extensions and connection to existing equipment.

3 Connection : accessible through front, connection to the lower load switch and earthing switch terminalsor the lower fuse-holders. This compartment is also equipped with an earthing switch downstream from the MV fuses for the protection units.

4 Operating mechanism : contains the elements used to operate the load switch and earthing switch and actuate the corresponding indications

(positive break).

5 Low voltage : installation of a terminal block (if motor option installed), LV fuses and compact relay devices.

If more space is required, an additional enclosure may be added on top of the cubicle.

Hunan Electric Union is a diverse electric equipment manufacturer group located in middle south of China.

Limit Innovation

We are in a traditional business since transformers and switches are developed over hundred years, even the so called “new technologies” of cast resin technology, vacuum arc distinguish technology and digital protection technology have been used for decades. Based on industry characteristics and to focus on products manufacturing itself, we implement a “limit innovation” policy on our mature products

1. Update products only if latest standards revision officially issued 2. Produce new products only if related technology are maturely developed. 3. Focus limit innovation on external updates to make products easy to use and transport.

Our Mission

After several decades of reform and opening, the development of China's electric power has made great progress, the manufacturing industries have gradually entered a world-class level, and many well-known international companies have chosen to set up factories in China. At the same time, we realized that many developing countries' power infrastructures are still very poor,so our mission is to provide the most cost effectiveproducts to world, and these products are transformed to meet relevant international standards (IEC and IEEE) based on widely used and proven reliable products in China in recent thirty years. Eventually, we could help the developing regions to update their energy quality and improve people’s life.
