Drop Wires No. 12, 10B, CAD55M & 10 to CW 1406, CW 1411, CW 1417 & CW 1378

 
Applications
 
  The drop wires are designed for use in local area network to link between pole and building or two buildings. The high tensile steel strength member wires are incorporated inside the cable to provide support. The cables can be used for crossing high voltage cables up to 11kV.
Standards
 
• CW 1406 (Drop Wires No.12 1 pair)
• CW 1411 (Drop Wires No.10B 2 pairs)
• CW 1417 (Drop Wires CAD55M 4 pairs)
• CW 1378 (Drop Wires No.10 2 pairs)
