•Conductor should comply with the requirements for Class 5 specified in IEC60228.
•The surface of conductor should be bright and clean no grease, no burr or bulge or faulted wire to damage the insulation.
•Every conductor coat with an isolated layer made from appropriated material.
The nominal value of the insulation thickness shall comply with IEC60227-7. The average value of insulation thickness should be no less than nominal value, and the thinnest part should be no less than 90% -1mm of nominal value.
Insulation adopts XLPE, whose property should comply with provisions in IEC60502-1. The insulation should be rapped on conductor tightly and easy to peel without damaging the insulation, conductor and coating. The surface of the insulation should be flat and color evenly.
Insulated conductors are separated by colors, and in accordance with DIN VDE 0293. Generally, adopted colors are brown, black, gray, yellow/green.
The shield adopts the structure of tinned copper braid and aluminum foil lapping. The density of tinned copper braid should be no less than 90%.
•The nominal value of sheath thickness should comply with the requirements of GB9330, and the average value of outer sheath should be no less than nominal value. The thinnest part should be no less than 85%-0.1mm of nominal value.
•Sheath is made from PVC mixed material, whose properties should comply with requirements for PVC/ST5 specified in sheet Two of IEC60227-1. The sheath should tightly rapped on stranded insulated core or coating. Meanwhile, the outer sheath should be clean and color evenly.
•The outer diameter should comply with requirements in GB9330. The color for sheath is grey or black.
•The ohmic value of conductor should be no more than specifications in IEC60228 at 20℃.
•Finished cables and insulated cores should withstand the rated AC voltage test of 2500V, and no breakdown in five minutes.
•The resistance of insulated conductor should be no more than 20MΩ•km.
•Mechanical and physical properties for finished cable insulation should comply with IEC60502-1.
•Mechanical and physical properties for finished cable sheath should comply with IEC60227-1.
•Finished cables should withstand the burning test specified in EN50265-2-1 or IEC60332-1.
•The shield impedance for finished cable should be no more than 10Ω/km at 20 ℃.
•Products can leave factory only after passing examination of technology department. Each package should be shipped with the product quality inspection certificate.
•Products should inspect according to GB9330. If it fails for the first time in sample inspection, then take another two samples to examine the failed project. If the two samples are acceptable, then the products are acceptable, false otherwise. The number of samples is accepted by both sides, or decided by manufacture at the time of no requirements from the buyer.
Mark、Packing、Transport and Storage
•There should be marks of maker, type, nominal cross-section area, voltage on the cable. The marks should comply with the requirements for conductor and color specified in DIN VDE 0293-308.
•Marks shall be legible, not easy to erase. The writing should be clearly visible after 10 times graze in absorbent cotton cloth.
•Cables can be packed both in coils and in circles. Cables in circle should be packed on cable specified in JB/T8137. Cables should be positive sealing, for those outside the circle, protective cover should be made. And the length of outside should be no more than 300mm.
•Tags should identify:
① Maker or trade-mark
② Type and specifications mm²,V
③ Lengths m
④ Manufacturing Date: Year Month
⑤ Product Standard Code
⑥ Correct direction for circles
Transport and Storage:
•The cables should avoid high temperature and cable circle does not allow flat.
•Forbid throwing circles with cable from high attitude and mechanical damage.
•Forbid lifting several circles at the same time. Circles should be put firm with appropriate methods to avoid tip over.
