Frequency converter cable symmetry design a: special cable for 1.8/3 kv and below frequency conversion motor, and symmetric 3 + 1 core and 4 core cable can only be used for the main power input cable, but it is best to use the symmetric structure of cable. Inverter and variable frequency motor and cable must adopt symmetrical cable structure, symmetrical cable structure with three core and 3 + 3 core two kinds, 3 + 3 core cable structure is a small four to three core insulation wire core in the fourth core (neutral) is decomposed into three smaller insulation wire core section, the three big three symmetrical string cable core cable, special cable for 6/10 kv frequency conversion motor, the cable structure and 6/10 kv power cable, ordinary ordinary power cable is three insulation wire core adopts copper tape screened after cabling.
