Thetest method shall comply with the provisions of GB/T 4909

 Insulation

The insulation is made of high-density polyethylene insulating material, which iscontinuously extruded on the conductor wire, the surface is smooth and flat, and itsthickness should meet the electrical performance of this technical specification. Theinsulated core wire adopts the color identification mark, the insulation color isuniform, and the following ten colors are used.

—–a line: white, red, black, yellow, purple

—–b line: blue, orange, green, brown, gray

HYAC communication cable line group

The pair set consists of two insulated single wires of different colors twisted together. They are all twisted to the right, and the twisting pitch is not more than 150mm

Cabling

Arrangement of cable core: the cable core of the cable is twisted by several sub-units, and wrapped with polyester tape. The recommended cable core arrangement shall bein accordance with the provisions of Appendix C of YD/T322-2013.

Suspension wires

Suspension wires and cable cores are arranged separately and in parallel, so that thecable transverse interface has an “8” shape structure, and the breaking force of thesuspension wires is less than or equal to 16KN

Aluminum-plastic integrated sheath (inner sheath)

The polyethylene double-sided aluminum-plastic composite tape is used forlongitudinal wrapping, the nominal thickness of the aluminum tape is not less than0.15mm, and the overlapping width of the aluminum-plastic composite tape is not lessthan 20% of the circumference of the cable core; the surface of the aluminum-plasticcomposite tape should be smooth, Smooth, uniform, free from impurities, wrinkles, mottling, and other mechanical damage defects. The aluminum-plastic composite beltshould be tightly extruded with a bonded polyolefin sheath. The outer surface of thepolyolefin outer sheath should be smooth, flat, free of holes, cracks, bubbles anddents
