Embodiment Construction
[0019] The novel adjustable electric wire of the present invention comprises an inner core, an insulating layer, a waterproof film and a connection interface. Among them, the waterproof film wraps the insulating layer, the insulating layer wraps the inner core, and the connection interface is used to connect the various wires. There are two types of cross-sections for the inner core, one is a circular cross-section and the other is a flat cross-section. The wire adopts segmented design, so the effect of adjusting the length can be achieved. The standard lengths include 1m, 2m, 5m, 10m, 20m and 50m, and the specific length can be selected according to the actual site requirements.
[0020] The wire is designed with an outsourcing waterproof film. On the one hand, it can play a good waterproof effect to prolong the service life of the wire. On the other hand, the easy replacement of the film can meet the requirements of field tests to a greater extent.
[0021] The insulation ...
