ZKP, ZKPB, ZKPz, ZKPBz
High-frequency communication cables ZKP, ZKPB, ZKPz, ZKPBz. TU16-505.233-96 These cables are designed for areal communication cable lines of K-60 transmission systems (for the frequencies up to 250 KHz). They provide distant feed transmission at up to 690 V AC 50 Hz.
- ZKP cables are sheathed with light-stabilized polyethylene, without shielding.
- ZKPB cables are sheathed with light-stabilized polyethylene, with B type shielding.
- ZKPz cables are sheathed with light-stabilized polyethylene, without shielding. The core is filled with hydrophobic filler.
- ZKPBz cables are sheathed with light-stabilized polyethylene, with B type shielding. The core is filled with hydrophobic filler.
Four copper solid conductors 1.2 mm in diameter are insulated with polyethylene and twisted into a spiral four around a polyethylene cord. The twist is wrapped with a blend of polyethylene and butyl rubber and shielded with copper, aluminium or aluminium polyethylene films.
