Sf6 Insulated Ring Main Unit Rmu

Production feature

-Fully Insulated and Sealed Design

ELE series switchgear contains a stainless steel tank filled with SFe gas, in which the primary live parts, the busbar and switch contacts are kept. The switchgear is equipped with DIN 47636 standard connecting bushings, which connect the inlet and outlet cables via fully insulated, shielded and sealed separable cable connectors. The gas box protection class reaches up to class IP67. Through special design and surface treatment, the parts outside the gas box have short period of anti-flood and anti-dewdrop functions.

-Standard Modular Design

Basic units include Loadbreak Switch Unit (Module C),Loadbreak Switch-fuse Combination Unit (Module T), Circuit Breaker Unit (Module V and Vo), Busbar Switch Unit (Module S, Module D, Module Vs, Module Vo ), Metering Unit(Module M), Busbar PT Unit (Module P). Cable feeder Unit Module B etc, Different modules can be combined and assembled in one SF6 insulated tank.

-Flexible Extensible Design

ELE series switchgear can be categorized into fixed inextensible ELE-F series switchgear in which basic units are combined in one tank, and ELE-E series flexible extensible switchgear. The ELE-E series provides the user with diversified

combinations via electrically connecting different tanks on the top with specific busbar connectors. These solutions maximally meet the requirements of complex and diverse power supply & distribution scheme all over China.

-Special Cable Branch Box Application Solutions

According to the domestic market requirements, the busbar of ELE series switchgear has outlet bushings on both sides. It is especially suitable for cable branch box with one or more load switches to get flexible and economic distribution solutions.
