cableThe power cable as one of our main products, the specification
and appliance of the power cable are listing as
follows: 1.The standardsThe power cable is mainly complying
with IEC 60502 standard, also can be produced according
to OEM requirements and other standards, such
as BS, DIN, ASTM, VDE, NFC standards, and so
on. 2.the construction of the power cable for different
voltage grade 2.1 low voltage cable power cableLow

cabel power cableVoltage grade is up to 35kv,cross-section area can
be up to 1000 sqmm (copper or aluminiun
conductor).Conductor long-time operating temperature is
90 degrees.In short circuit, conductor highest temperature
should be not more than 250 degrees.1kv-35

conditions: for lyaing under ground with large different
altitude, be able to bear external machanical force and
moderate pulling force. 3. the power cable's
characteristic:3.1 long time operating temperature for cable
conductor is 90 degrees.3.2 the highest temperature of the
conductor in short circuit (no longer than 5 seconds) in not more
than 250 degrees,if a joint is in the cable, the temperature of the
tinning welding joint is not more than 120 degrees, compressing
joint not more than 150 degrees and electro-welding joint not more
than 250 degrees.3.3 no drop in limited provided there is full
mechanical tention when cable is laid. It si forbidden to lay cable
in iron-pipe or to fix cable by circling around the cable with iron
materials.3.4 being laid, the minimum temperature of the cable
shall not be lower than zero degree. In the case of lower
temperature, heating measures shall be taken. We can also
supply the OEM and customized products according to your request/*
