Brief Introduction
PVC/XLPE power cable is used to transmit and distribute power in
power transmission and distribution system of *5kV or lower. It is
generally applied to the fields including power, construction,
mines, metallurgy, petrochemical industry and communication in
complete replace of oil immersed paper insulated power cable and in
partial replace of PVC insulated power cable.
Standard
The products can be produced according to our factory specification
which is equivalent to the standard IEC****2. The factory can also
design and manufacture special power cable according to the other
standards required by the customers.
Properties of PVC Power Cable
1. The long-time permissible working temperature of cable
conductive core is not more than *0 degrees.
2. During short circuit (max permanent time is not more than 5
seconds), the max temperature of cable conductor is not more than
**5° C.
3. The difference level of laying cable is not restricted. When
laying the cable, ambient temperature is not lower than 0°
C.
4. They have good chemical stability, and properties of acid
resistance, alkali resistance, salt resistance, oil resistance,
solvent resistance and flame resistance.
Properties of XLPE Power Cable
1. The highest allowed operating temperature of conductor for
long-term working is *0 degrees.
2. In short circuit (Max long term is no more than 5 seconds). The
highest temperature for conductor is no more than **0
degrees.
3. The cable is laid without horizontal drop limit. The environment
temperature should be no lower than 0 when lay. Otherwise it should
be preheated.
4. Excellent electrical performance, resistance to chemical
corrosion.
5. Can stand advisable traction when laid. Can stand traction from
Outside. Left low smoke halogen-free after burned. Retard the
burning of the cable.
