Power cables with copper tendons, with isolation from silan-sewn together polyethylene in PV shell
CONSTRUCTION
1. CURRENT IS CONDUCTING WIRE copper, onewire or multiwire, round or sector form, 1 or 2 classes for 22483.
2. ISOLATION from silan-sewn together polyethylene. The isolated tendons of cables of multicores have the distinctive colouring, which can be not only continuous but also as a longitudinal bar breadthways no less than 1 mm.
3. TWISTING the isolated tendons of cables are twisted up in mandrel. Cables are executed four- and five-tendons and have all tendons of identical section or one tendon of less section (zero or grounding) in cables of four-tendons.
4. HALF-LENGTH ISOLATION laid on over the twisted up tendons from chalk of the filled not vulcanized rubber mixture or from PVC plastic.
5. SHELL from PVC plastic.
APPLICATION DOMAIN
For a transmission and distributing of electric power in stationary options on nominal variable tension 1 kv frequencies 50 Hz. in networks with isolated or earthed neutral.
Cables type of is intended for the gasket of single busses of cables in buildings of cables, apartments in default of danger of mechanical damages.
