  • SF6 Gas-Insulated Transformer | Transformer | MEIDENSHA

    SF6 gas known for its non-flammabilit and coordinative ability with environmental conditions. Lt was widely used in underground substations and inddor substations at underground shopping areas, traffic systems, and public structures. SF6 Gas-Insulated transfomers are designed to reduce fire hazards and less risk on the environment. By directly coupling with gas-insulated Switchgear, substation space can be minimized as the result of compact facilities.

    The splice joint should be made through the material in a dimension or angle so that the compression force is pushing the joint together. The general rule is that the splice length should be a minimum of three times the material thickness. Scarfed joints can be rejoined using a hot vulcanizing process or by using a proper adhesive.
