■ Technical Data
1. When the temperature is at +20℃, the DC resistance of wire core of finished cable should be in conformity with the regulations of GB/T3956.
2. When the temperature is at +20℃, the insulation resistance at the insulation core surface of UZ type cable should be less than 100M per 1km. When the temperature is at +20℃,the insulation resistance between the space of insulation wires of U,UP,UCP type cable should be less than 100M per 1km.
3. The space between the control wire cores of UZ type cable, UC and UCP type cable should withstand AC 50Hz, 2000V voltage test for 5 min mutes. The space between the wire cores of U, UP, UC and UCP type cable should withstand AC 50Hz, 3000V voltage test for 5minutes.
4. When the cross section of U,UP,UC,and UCP cable is 16 mm2 or more, it should possess mechanical compact and compressive property.
5. The standard sheath cable for mine should meet relative regulations of MT386.
