Cable Branch Box with SF6 Load Break Switch<\/strong><\/h4>\n

\u00dcr\u00fcne Genel Bak\u0131\u015f<\/strong><\/p>\n

The ring-network type cable branch box with SF6 load break switch is composed by connecting the SF6 load switch with related cable connector accessories. It can directly interrupt load current and improve power supply reliability. The enclosure is made of high-quality steel plate with scientific air inlet and outlet design, providing good heat insulation and ventilation. The SF6 load switch uses SF6 gas as arc-extinguishing and insulating medium, with contacts sealed in a reinforced epoxy-resin shell filled with SF6. Touchable shielded synthetic-rubber cable incoming and outgoing lines are connected through cable connectors to integrated bushing seats or special busbars. Inside the box, cross connectors and T-connectors can realize fully insulated and fully sealed connection with the SF6 load switch. The product is suitable for cable connection, branching, power transfer and distribution in cable networks, and offers maintenance-free operation, corrosion resistance, compact size, safety, reliability, compact structure, simple installation and flexible operation.<\/p>\n
