Title:
POWER CABLE OF WHICH ELECTRICAL LEAKAGE CAN BE DETECTED BY LEAKAGE PROTECTOR
Document Type and Number:
WIPO Patent Application WO/2023/221151
Kind Code:
A1
Abstract:
A power cable of which electrical leakage can be detected by a leakage protector, comprising an outer sheath layer (1), a live wire, a neutral wire and a ground wire being arranged in the outer sheath layer (1). The live wire comprises a live wire core (21) and, sequentially sleeving the outer side of the live wire core (21), a live wire first insulation layer (22), a live wire shielding layer (23) and a live wire second insulation layer (24). The neutral wire comprises a neutral wire core (31) and, sequentially sleeving the outer side of the neutral wire core (31), a neutral wire first insulation layer (32), a neutral wire shielding layer (33), and a neutral wire second insulation layer (34). The ground wire comprises a ground wire core (41) and a ground wire insulation layer (42) sleeving the outer side of the ground wire core (41). When the live wire shielding layer (23) or the neutral wire shielding layer (33) breaks, or the live wire and the live wire shielding layer (23) are short-circuited, or the neutral wire and the neutral wire shielding layer (33) are short-circuited, a leakage protector detects an anomaly signal of the power cable, and cuts off the electric connection of the live wire and the neutral wire, thus preventing a fire caused by short-circuiting of the live wire core (21) and the neutral wire core (31) when the power cable is damaged.
