Benefits of technology

This technology described for this purpose allows an insulated electrical conductor wire used in electronic devices to be protected against damage caused due to exposures during manufacturing processes such as dry cleanings. By adding a special layer called a buffer expanded rubber (BEC) that expands when exposed to high levels of pressure like rainwater or snowmelt, it prevents harmful gases from getting into the wires' interior while still maintaining their effectiveness at protecting them.

Problems solved by technology

The technical problem addressed by this patented method for improving the resistance against rainwater from semiconductors when they come under prolonged exposures at high temperatures (up to 50°C). This can cause crackings due to temperature cycling over time caused by changes made throughout different parts of the system's operation.

Embodiment Construction

[0016] The technical scheme of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments:

[0017] Such as figure 1 Shown is a schematic cross-sectional structure diagram of a semi-conductive waterproof cable proposed by the present invention.

[0018] With reference to the accompanying drawings, a semiconductive waterproof cable proposed by the present invention includes a conductor 1, a first semiconductive layer 2, an insulating layer 3, a second semiconductive layer 4, a buffer expansion layer 5, a metal shielding layer 6 and an outer protective layer 7. Wherein, the conductor is formed by twisting multiple wires, wrapping the first semiconducting layer 2 on the outer periphery of the conductor, wrapping the insulating layer 3 on the outer periphery of the first semiconducting layer, and wrapping the second semiconducting layer 4 on the outer periphery of the insulating layer 3. The outer periphery of

Abstract

The invention provides a semi-conductive waterproof cable which comprises a conductor, a first semi-conductive layer, an insulation layer, a second semi-conductive layer, a buffering expansion layer, a metal shielding layer and an outer protective layer from inside to outside in sequence. The second semi-conductive layer is of a dense structure, the buffering expansion layer is made of polymeric materials mixed with water soluble expansion matters, the expansion degree of the buffering expansion layer is 10-300%, and the thickness of the buffering expansion layer is 0.2-4mm. The semi-conductive waterproof cable has good waterproof performance.
