Tinjauan Produk
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.
Fungsi dan Fitur
| Fitur 1 | One or more SF6 load switches can be installed on each line, replacing part of the ring main unit and reducing project cost. |
|---|---|
| Fitur 2 | The three-position SF6 load switch with rotary arc chamber can isolate partial outage faults and reduce the impact of outage. |
| Fitur 3 | A five-prevention interlock is arranged between the switch and enclosure; incoming and outgoing cable headers are equipped with high-voltage live display devices for safe inspection and operation. |
| Fitur 4 | Fully insulated, fully sealed, compact, maintenance-free, dustproof, flood-resistant and corrosion-resistant, suitable for harsh environments. |
| Fitur 5 | Full-shield cable connector requires no insulation distance and ensures personal safety. |
| Fitur 6 | Flexible incoming and outgoing arrangements meet multiple outgoing line requirements. |
| Fitur 7 | Front-door design with external mechanical lock. |
