Earthing switch operation mechanism interlock device Suppliers – YFRM6-12 Combined Fully Enclosed GIS – Timetric
Earthing switch operation mechanism interlock device Suppliers – YFRM6-12 Combined Fully Enclosed GIS – Timetric Detail:
General
YFRM6-12 type inflatable switchgear is a completely sealed system while all live parts and switches are installed in a stainless steel shell. The entire switchgear will not be influenced by surroundings, ensuring operational reliability and personal safety, and maintenance-free operation.By combining expandable busbars, any combination can be achieved to realize full modularity. For extended busbar safety insulation and shielding, it is highly reliable and safe. The YFRM6-12 inflatable switchgear can also provide TV-based automation solutions, forming the concept of intelligent switches and minimizing on-site installation and commissioning.
YFRM6-12 ype inflatable swichgear is divided into non-extended standard configuration and extensible standard configuration.It has extremely exceptional flexibility due to the combination of full and half modules and its own scalability. lt has a long life for over 30 years operated under 20 ℃ indoor condition.
Modular design
YFRM is a modular design. The basic module units are load switch modules, combined electrical modules and other special function modules. Any combination of these modules formeda common box structure. In the combination, any function is approximately the same as the internal structure of the basic module.
Normal use condition
I is applicable in the place with high and lowtemperature(-40℃-+40℃), humidity and salt. I can also be used in mine and the place wih high litude. Short term water in 24 hours does not affect the use. Note: If higher altitude, please specify the altiude.
