Abstract

The invention discloses a photoelectric composite waterproof flame-retardant cable for a photovoltaic system and processing equipment of the photoelectric composite waterproof flame-retardant cable, and relates to the technical field of photovoltaic cables. On the structure basis of the waterproof outer sheath layer, the anti-corrosion stainless steel band armor layer, the waterproof flame-retardant filling layer, the electric transmission unit and the optical transmission unit, the waterproof wrapping tape layer, the metal shielding layer, the insulation shielding layer, the insulation layer and the conductor shielding layer are arranged outside the conductor of the electric transmission unit, and the waterproof wrapping tape layer prevents water from entering; the cooperation of the metal shielding layer and the conductor shielding layer improves the anti-electromagnetic shielding performance of the conductor, and the cooperation of the insulation shielding layer and the insulation layer improves the insulation antistatic performance of the conductor. The cable has good strength, waterproof and flame-retardant performance and anti-electromagnetic shielding performance, and the current-carrying capability of the cable is improved. The processing equipment has the functions of conveying, extruding, shaping and pressing, winding and cutting the anti-corrosion stainless steel band armor layer, and the photoelectric composite waterproof flame-retardant cable with the waterproof outer sheath layer is obtained.

Description

technical field [0001] The invention relates to the technical field of photovoltaic cables, in particular to a photoelectric composite waterproof and flame-retardant cable for photovoltaic systems and processing equipment thereof. Background technique [0002] Photoelectric composite cable is suitable for broadband access network system as a transmission line. It is a new type of access method. It integrates optical fiber and power transmission copper wire, and can solve the problems of broadband access, equipment power consumption, and signal transmission. The working environment of the photovoltaic power generation system is open air, and the supporting power cables are laid in the open air. Due to the particularity of the working environment of the photovoltaic power generation system, although the commercially available conventional power cables can meet the current transmission requirements, the application effect cannot meet expectations. [0003] The patent applicatio...
