Abstract
Description
Technical Field
[0001] This utility model relates to the field of wiring technology for electrical equipment, and in particular to a sensor indicator cable. Background Technology
[0002] Electricity is a fundamental guarantee of social life and is closely related to the national economy and residents' lives. The safety and stability of the power transmission system are of paramount importance. In order to better protect outdoor power transmission cables, this technical design aims to provide a warning and indicator light cable product to mark the presence of AC power cables, remind nearby residents to stay away from AC power facilities, avoid unnecessary safety hazards, and prevent residents' activities from damaging power facilities. In power transmission systems, outdoor power cables serve as crucial power carriers, and their safe operation is directly related to the safety of life and property of nearby residents and the stability of the power system. However, existing outdoor power cables lack effective warning signs, often leading to cable damage or electric shock accidents due to residents' lack of awareness of cable locations and activities such as construction or play in the vicinity. Traditional warning methods often involve setting up warning signs, but these signs are easily damaged or displaced by the natural environment, and their effectiveness is poor at night or in inclement weather. Furthermore, some warning devices require additional power, increasing energy consumption and leading to complex wiring and high maintenance costs. Therefore, there is an urgent need for a sensor-activated indicator cable that can autonomously sense power, requires no additional power supply, adapts to complex outdoor environments, and provides long-lasting warnings. This cable would mark the location of power cables, alert residents to stay away, and ensure the safety of electrical facilities. Utility Model Content
