Tiankang YJGLHV aluminum alloy cable

Product Introduction

TiankangYJGLHVAluminum alloy cable,YJGLHBV cable

Also known as TC90 (-40) YJGLHV, YJGLHBV, etc

Alternative copper cable: YJV (e.g. YJV 4 * 70+1 * 35=YJLHV 4 * 120+1 * 70)

  Product Overview:

5.1conductor

5.1.1cableThe aluminum alloy conductor material must be certified by the Aluminum Industry Association and use high-performance materialsAA8000series8030aluminum alloy(Third party materials must be provided)Alloy composition testingreport, conductorThe performance should comply withGB/T30552－2014 Aluminum alloy wire for cable conductors，(A compressive creep performance testing report issued by the National Center for Quality Supervision and Inspection of Electric Wires and Cables is required)；The direct current resistance of the conductor meets the requirementsGB/T3956-2008The regulations.

5.1.2 The surface of the conductor is smooth and free of burrs, sharp edges, and protruding or broken single wires that damage the insulation.

5.1.335mm²Conductors of specifications and above should adopt a twisted wire structure.

5.1.4strandThe completed conductor should undergo sufficient heat treatment for a certain period of time.

5.2 insulation

5.2.1Select high-performance cross-linked polyethylene insulation material as the insulation material（XLPE）The insulation is tightly extruded onto the conductor and easily peeled off without damaging the conductor; The insulation surface is flat and the color is uniform.

5.2.2The insulation material should have a certain resistance to salt spray corrosion and meet the requirements of environmental testing for electrical and electronic products (test reports must be provided).

5.2.3The nominal thickness of the insulation complies withGB/T12706.1-2008The regulations(table1)The average insulation thickness shall not be less than the specified nominal value, and the thickness of the insulation thin point shall not be less than the nominal value90%-0.1mm.

5.2.4There are no visible defects such as bubbles and sand holes on the cross-section of the insulation layer.

5.2.5The identification mark of the insulated wire core conforms toGB6995.5-2008The regulations.

5.3Cable cores and fillers

The gaps between the cable cores can be filled appropriately after cable formation to ensure roundness.

5.4inner liner

5.4.1The cable core has an inner lining layer, which adopts a winding type. The working temperature of the winding inner lining layer is adapted to the working temperature of the cable.

5.5Cable outer sheath

5.5.1The sheath material of the cable adopts high-performance polyvinyl chloride sheath material, and the sheath of the cable is evenly extruded outside the cable core, with a smooth surface and uniform color.

5.5.2The sheath material should have a certain resistance to salt spray corrosion and meet the requirements of environmental testing for electrical and electronic products (test reports must be provided).

5.5.3The thickness of the sheath meets the requirementsGB/T12706.1-2008The regulations.

5.5.4The armor of the cable must be usedNon magnetic material with high strength and excellent corrosion resistanceAA5xxxSeries aluminum alloy, with a self-locking structure, and the armor layer's resistance to lateral pressure is not less than4380N/m*R.(A test report must be provided).

5.6Cable connection fittings

Cable connection fittings (direct connection fittings, branch connection fittings, wiring terminals) should meet the requirements of the "Rated Voltage35KV(Um=40.5KV)Crimping and mechanical connection fittings for conductors of power cables and below Test Methods and RequirementsGB/T 9327-2008(Modified using)IEC 61238-1:2003Standards must be provided and1000 thermal cycle test report for copper aluminum transition terminal (the conductor used for testing must be self-produced).
