Product Description

Description

SF6 Gas Recovery, Purification & Refilling Unit is main used for manufacture, installation and maintenance of SF6 electrical equipments, such as circuit breakers, GIS(gas insulated switchgears), high-voltage transformers, high-voltage transmission lines, substations, etc. It is composed of vacuum system, compression systems, purification systems, storage system, condensing system and re-filling system.

Features

1. The use of foreign companies advanced principles and technology, advanced design, functional and reasonable structure, the operation simple and clear.

2. Adopts imported USA semi-enclosed compressor, stable performance and service life is greatly extended.

3. Vacuum system uses Germany vane vacuum pump, fast vacuum pumping speed.

4. SF6 Gas Recovery, Purification and Refilling Machine uses USA Neil filter with two-stage built-in electric heating and efficient absorption (without frequent replacement of adsorbent), greatly improving quality of SF6 gas

5. The latest patented SF6 special instruments and valves, more reliable instrument ball valve.

6. Interlocked protective system can avoid overload, over voltage, electricity leak and prevent any damages to equipments due to operating error or power failure.

8. The SF6 Gas Recovery Machine uses air-cooler, can be used without external water conditions.
