Conductor should comply with the requirements for Class 5 specified
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
The nominal value for thickness of sheath should comply with DIN
VDE 0282-4. Meanwhile, the average value of should be no less than
nominal value while the thinnest part should be no less than
85%-0.1mm of the nominal value.
Sheath is made from oil-resist insulated PVC, whose properties
should comply with requirements for 3GI3 specified in DIN VDE 0207
T20. The sheath should tightly rapped on stranded insulated core or
coating. Meanwhile, the outer sheath should be clean and color
Insulated conductors are separated by color yellow and green, and
in accordance with requirements of DIN VDE 0293.
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
Mechanical and physical properties for finished cable sheath should
comply with requirements in DIN VDE 0282-4.
Finished cables should withstand the burning test specified in
EN50265-2-1 or IEC60332-1.
Finished cables should withstand the oil-resist test specified in
DIN VDE 0473 6081-2-1.
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 DIN VDE 0282-4. 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
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
Forbid throwing circles with cable from high attitude and
Forbid lifting several circles at the same time. Circles should be
put firm with appropriate methods to avoid tip over.
