Mine communication cable mhyvp, can use 220V electricity?
However, in order to be safe, the 500V shake table is used to measure the insulation between the cable core and the core and shield. As long as the insulation resistance is greater than 1M, it can be used safely.The conductor of the cable section is nominal (7/0.28 or 7/0.37 structure) 0.43 or 0.75 mm, two shares of the total cross section is 0.86 or 1.5 mm (two strands parallel reference ampacity of 6 or 12 Amperes), smaller than you not the ordinary 4 mm square wire load flow, do not know the specific cable conductor you use the nominal cross section, also don't know you need to provide 220 alternating current, load current much.
Standard requirements: AC withstand voltage performance: cable insulation wire core and insulation wire core and shielding room should be able to withstand 1 minutes 1.5kV AC withstand voltage test, shall not have breakdown and flashing phenomenon. Therefore, AC 220V AC should be no problem.
MHYVP 2X2X7/0.37 polyethylene insulated and sheathed coal mine signal cable, used for signal transmission in the place where electric field interference is big, can be used for fixed laying. The implementation standard is MT818-1999Can pass 220V AC, the key depends on the insulation pressure, nominal insulation thickness is 0.45mm, insulation is polyethylene.
