DFWK-102K Outdoor Opening And Closing (High Voltage Cable Branch) Fully Sealed
Product Description:
The inner layer is used to equalize the internal electric field and the outer shield layer is used to protect the cable head from zero potential. The inner layer of the lower end of the stress cone is in close contact with the semiconductor layer of the cable, while the outer semiconductor layer is in close contact with the outer semiconductor layer of the cable head and is grounded through the earthing hole of the cable head. This not only solves the problem of electric field concentration in the cut off of the outer shield layer of the cable, but also keeps zero potential in the outer shield layer of the cable to ensure personal safety.
The front connector of the touchable cable is directly installed on the casing of the equipment, and then it can be connected with the rear connector of the touchable cable to form a multiway outlet line or to connect with the arrester to provide overvoltage protection for the power network.
Product Advantage:
●Prefabricated live touchable silicone rubber cable head, fully sealed, fully insulated, maintenance-free and reliable for personal safety;
●Compact structure, compact appearance, stainless steel bilayer box, service life can reach more than 20 years;
●On the premise of not affecting the operation of the main network, the regional blackout maintenance is realized and the blackout range is reduced;
●Can be equipped with one or more sf6 load switches, flexible wiring mode, branch outline up to 8 circuits;
●Optional arresters, short-circuit fault indicators, current-limiting fuses and so on, to meet various user requirements.
