Insulation resistance between the main cores and between the main cores and the ground wire, converted to +20°C, is not less than 100MΩ?km.
2. The transition resistance of the main core shielding layer is not more than 3kΩ when converted to 20°C.
3. Product Standard: MT818.5-1999.
4. The MYP type cable consists of 3 main cores with insulated shielding and a ground wire covered with a semi-conductive rubber layer, which is wrapped around a semi-conductive rubber layer core and twisted into a cable. The outside is sheathed with a black chlorinated polyethylene rubber sheath or a black chloroprene rubber sheath.
5. Conductor Core: Made of soft copper wire, its performance meets GB/T3956-1997.
6. Insulation: Utilizing XJ-00A rubber as specified in GB7594.2-1987.
7. Core Identification: Utilizing insulated color coding for identification, with the main cores being red, green, and white.
8. Ground Wire: Semi-conductive rubber sheathed.
9. Insulation Shielding: Wrap semi-conductive tape over the insulating surface.
10. Cable making: Consists of 3 main cores and 1 earth wire wrapped around a semi-conductive rubber core pad in a right-hand lay.
11. Sheath: Made of rubber type XH-03A according to GB7594.7-1987. The oxygen index of the sheath rubber is ≥40.
12. The flame-retardant performance of the finished cables meets the requirements of MT386-1995.
13. Cable Marking: The cable surface is imprinted with the model, voltage, specifications, and manufacturer's name.
