Place of origin: henan, china (mainland) Brand name: zms cable Model number: 110kv cable Insulation material: xlpe Type: high voltage Application: power station, underground Conductor material: copper Jacket: pvc Product name: 110kv cable Rated voltage: 110kv-500kv Rated temperature: 90 Screened: corrugated aluminum Customized: acceptable Core number: 1, 3 Conductor type: stranded Standards: iec, gb Company nature: manufacturer

XLPE insulated high voltage power cable is used to transmit power on the power transmission and distribution line of A.C.50Hz, rated voltage 35kV or lower, and also used for Subway,Power station,Factory and Mine.It can be installed underground, in pipe, in trench or in tunnel. XLPE Cable not only has excellent electric character, mechanical character, heat and aging-resistant character, environmental stress-resistant character and chemical corrosion- resistant character, but simple structure, light weight, no restriction by laying drop, and high temperature allowance for long-term working as well.

Specific property for usage of 110kv~220kv xlpe high-voltage cable 1. Cable's conductor highest working temperature is allowed up to 90⺠c, and overload when meet an emergency is 130⺠c, when short circuit (in â?¤ 5 seconds) the highest temperature is 250⺠c 2. When installing or laying cable, the ambient temperature should be less than -20⺠c, and have to give a preheat to cable. 3. The minimum bending diameter(in follow the table): Note: in form, d0 is a real test value to cable's outer diameter. 4. Allowed biggest axial traction force to outer diameter when laying cable (not consider the radial lateral-pressure at bent set ion) t=kã? core no. Ã? section (kg), in formula, the coefficient k value should be: the copper core get 7, the aluminum core get 4. 5. Allowed biggest lateral-press p, when cable is being bent The single core cable is required pâ?¤ 500kg/m. P=t/r (t is indicated axial traction force; r is indicated radius of bent-wheel), knowing from above formula, as the traction force is made up by length and weight of cable. So it lets p to applying requirement as above. Then the diameter of bent-wheel should be widened. 6. Cable laying is not being restricted by drop.
