LAP Cable

Lap cable Polythene insulationed Lap sheath cable Description: Twisted pair cable with solid /foam skin polythene insulated copper conductor, lap sheathed ( laminated aluminium shield polyethylene sheathed ) cable for local communication. Application: Lap cable is designed for telephone exchange area and trunk line. Construction: Conductor Solid annealed copper wire, sizes: 0.4 mm to 0.9 mm. Insulation Pe, color code in accordance with standard telephony industry code. Twisted pairs Insulated conductors twisted into pairs. Varying lay length is designed to minimize the cross talk and capacitance unbalance. Cable core 10 or 25 pairs are stranded to form a group called unit. Units/super units make up cables of 50 pairs and above. Core wrap Non-hygroscopic dielectric tape applied hellically or longitudinally over cable core fully filled with filling compound. Screen Electrically continuous 0.2 mm thick aluminium tape coated with co-polymer on both sides applied longitudinally and overlapped to form a moisture barrier. Jacket Black ldpe Identification & Length marking Manufacturer's identification, cable type, conductor size, year of manufacture are marked on jacket at one meter intervals (can be also as per customerí»s request) 1000m or 500m per durm
