URD Copper Core, XLPE Insulated, Corrugated Aluminium Tape, PE Outer Sheath, Longitudinal Water Proof Power Cable
Construction of the URD Copper Core, XLPE Insulated, Corrugated Aluminium Tape, PE Outer Sheath, Longitudinal Water Proof Power Cable
Conductor:
Cross section up to 3000mm2.
Conductor cross section of 800mm2 or below is stranded through compacting round core, with better roundnessand higher compacting coefficient. Conductor cross section more than 800mm2 is made by segmentof Milliken methodto minimize skin connecting and alternating current impedance and increasepowertransmissioncapacity of cable
Insulation:XLPE, self-gravity feeding under 1000 level ultra-clean environment.
Insulation method:VCV
Metallic screen/sheath: 1) corrugated aluminum tape
2)copper wire + laminated tape
Sheath: PVC,MDPE, HDPE.
Application features
1, Conductor permmisble max. long-time operation temperature: 90°C
2, Conductor Max. short circuit temperature(max. sustaining period not exceeding 5s): 250 °C
3, Allowable Min. bending radius when laying cable, generally 20 times of the cable diameter.
Consitions deciding the different specifications:
1,Single loop, central distance 250m between phase at the operation temperature of conductor 90 °C
2,Metallic screen grounding method: earth atone end or cross bonding earth at two ends.
3, In air: temperature 40 °C , without direct sunlight; directly buried;soil temperature 25 °C , soil thermal resistance coefficient 1.2 °C , m/w °C buried depth 1m
4, Short circuit current shall be calculatedat IEC949 (under adiabatic condition), short circuit start temperature:conductor 90 °C , metal sheath 80 °Cand short circuit temperature 250 °Cfor 1 sencond.
