Sealing end bells of indoor unit, Armature for overhead power transmission lines

In distributing devices in places of their accession to the equipment apply different types of end seals (couplings) to termination of cables. End sleeves for power cables with paper and plastic insulation should be carried out according to technical documentation. Data on the choice and a scope of end seals (couplings) of indoor unit are provided in the table. Dry seals with polyvinyl chloride tapes, just as (couplings) of indoor unit and their application on application in rooms is allowed to apply temporarily them before mass deliveries of epoxy seals of designs of end seals and seal in the form of rubber gloves, cannot be applied in wet and crude rooms which substations of networks of the city and KGP of outdoor unit treat. For termination of cables to 10 kV inclusive use end seals of KVE with the body from an epoxy compound, simple in mounting and fireproof. End internal epoxy seal of KVED with two-layer tubes is shown in fig. 1, and. The distance between tubes on a gossan from the epoxy body for cables on voltage of 10 kV should be not less than 25 mm. In seal of KVED put on two-layer tubes which external layer from polyethylene isolation of cable cores, and internal — from polyvinylchloride.
