Abstract
The invention discloses a cable special for a frequency changer. The cable special for the frequency changer comprises three main wire core units and three ground wire core units. Each main wire core unit comprises a main wire core, a main wire core insulating layer and a main wire core shielding layer, wherein each main wire core insulating layer and each main wire core shielding layer wrap the outer portion of each main wire core; each ground wire core unit comprises a ground wire core, a ground wire core insulating layer and a ground wire core shielding layer, wherein each ground wire core insulating layer and each ground wire core shielding layer wrap the outer portion of each ground wire core; a taped covering layer, an inner shielding layer, an inner protecting casing layer, an outer shielding layer and an outer protecting casing layer are arranged on the outer portions of the main wire core units and the outer portions of the ground wire core units in sequence. Through the mode, the cable special for the frequency changer has good shielding effects and reduces electromagnetic interference.
