Description

Technical Field

[0001] The utility model relates to the technical field of wires and cables, in particular to radiation cross-linked halogen-free low-smoke flame-retardant insulation sheathed fire-resistant photovoltaic cables and production equipment. Background Art

[0002] Cable is a general term for items such as optical cables and electrical cables. Cables have many uses, including controlling installation, connecting devices, and transmitting power. They are common and indispensable in our daily lives. However, because cables carry electricity, they require special care when installing them.

[0003] For example, the patent application CN216311389U discloses a halogen-free, low-smoke, flame-retardant polyolefin insulated and sheathed fire-resistant power cable, comprising an insulated core, a protective reinforcement plate, a tape layer, and an outer sheath. The insulated core is located in a core mounting cavity separated by a partition plate within the protective reinforcement plate. The outer portion of the protective reinforcement plate is provided with arcuate convex edges and arcuate concave edges at intervals. Pressure-resistant grooves are defined at both ends of the arcuate convex edges. Pressure-resistant balls are embedded in the pressure-resistant grooves and are tangent to the tape layer. A plurality of elastic rubber blocks are provided between the two pressure-resistant grooves. An elastic cavity is defined in the middle of the elastic rubber blocks. The elastic balls are embedded in the elastic cavity and are tangent to the tape layer. A flame-retardant filler is filled between the arcuate concave edges and the tape layer. An outer sheath is provided around the outer periphery of the tape layer. The outer sheath is composed of an outer sheath, an inner sheath, and a reinforcement strip. The outer sheath and the inner sheath are correspondingly engaged, and a trapezoidal buffer groove is defined on the outer wall of the inner sheath for the movement of the reinforcement strip.

[0004] However, the existing cables do not have high halogen-free and low-smoke flame retardant properties, so their lifespan will be shortened when used under certain circumstances. At the same time, when existing cable production equipment is cooled, the cables usually cause a large amount of water stains to move, resulting in water waste, soaking the ground, and possibly causing water stains to be brought into the production equipment, causing damage to the equipment.
