Wind energy power cable is applicable for flexible, free hanging
and fixed installation. In the free-hanging installation
environment, the cable can be reversed with fan freely.
The product is applicable from stator of wind power generator to
phase and PE line of power distribution cabinet, from rotor of wind
power generator to phase line of power distribution cabinet, and
from power distribution cabinet to phase and ground line.

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.
