Application:Suitable for wind turbine nacelle: cable, tower, the wind turbine to box transformer substation.
standards:
Structure:
content:The characteristics of cable Features of operating environment: long-term operation in the room, hung vertically laid, frequent torsion (automatic yaw wind), contact with oil (part), seawater corrosion (special). Vertical laying characteristics: high mechanical strength, soft (torsion), oil resistance, low temperature resistance requirements.
Types of cables Applicable to the cabin: soft cable, control cable, chain cable (for the rotor circuit), the data line. Applicable to the tower: wire cloth (lighting), power cable (fixed installation and torsional section two.).
Use characteristics 1 cable with rated voltage of U0/U were: 450/750V, 0.6/1KV, 1.8/3KV. 2 the allowed working temperature of cable conductor are respectively: the voltage level of 450/750V at 70 ℃ The voltage level of 0.6/1KV, 1.8/3KV at 90 ℃. The minimum bending radius of 3 cable is 6 times that of cable diameter. 4 cable lowest ambient temperature: normal type: -25 ℃; cold resistance: -40 ℃; resistance to cold sex: -55 ℃.
