Connecting couplings for single-conductor screened cables with plastic isolation and the aluminum wire screen on tension of 10, 20 and 35 kV
-
Here connecting couplings for single-conductor cables with plastic isolation and the aluminum wire screen of 10, 20 and 35 kV are presented.
For example: APVKSV, PVKSP, APVKSP, PVKSP, APVPG, Apvp2g, PVP.
For cables with the aluminum wire screen. The cable settles accounts so that to exclude breaks screen a provolok which connect special connectors to sryvny bolts. On the semiconducting screen the thermoseated tubes for protection against mechanical connectors are established.
The place of a cut of the screen podmatyvatsya by a yellow tape of filling of emptiness, and then on a cut the tube leveling intensity of electric field is established. Veins connect mechanical the connector delivered in a set. The connector is wrapped in a mastic plate for alignment of intensity of the field.
On area of connection the three-layer elastomeric tube providing the uniform thickness of isolation and restoring the polymeric screen in a junction takes seat. A copper grid restore the metal screen. The aluminum screen is restored by mechanical connectors.
External sealing is carried out by means of the thick-walled thermoseated tube with thermofusible glue inside.
