Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic cables, in particular to a waterproof and corrosion-resistant photovoltaic cable. Background Art

[0002] Photovoltaic cable is a special cable product, which is mainly used to connect various components and equipment in photovoltaic systems.

[0003] The main structure of photovoltaic cables includes conductors, insulation layers and sheaths, and they are divided into two types: DC cables and AC cables. DC cables are used to connect photovoltaic modules, strings, DC distribution boxes and inverters, while AC cables are used to connect inverters to low-voltage distribution systems, as well as low-voltage distribution systems and transformers, transformers and power grids or users.

[0004] Existing photovoltaic cables are mainly protected by their outer sheaths. However, photovoltaic cables are often used in harsh outdoor environments. The rubber material on the surface is easily corroded by environmental factors (such as water, oxygen, acid, alkali, etc.), resulting in corrosion on the cable surface. During long-term use, problems such as structural embrittlement and cracking may occur. When encountering rainy and snowy weather, water may easily enter the photovoltaic cable. Therefore, the current photovoltaic cables are improved. Utility Model Content

[0005] The utility model is a waterproof and corrosion-resistant photovoltaic cable proposed to solve the shortcomings in the prior art.

[0007] Two cuttable insect-proof strips are symmetrically fixed and bonded to the outer surface of the photovoltaic cable body.

[0008] Furthermore, the cable core assembly includes an inner lining, and the inner lining is fixedly arranged on the inner side of the waterproof layer, the inner surface of the waterproof layer is fixedly equipped with a filling layer, the inner surface of the filling layer is fixedly equipped with four insulating layers, and the inner surfaces of the four insulating layers are all fixedly equipped with cable cores. The main function of the insulating layer is to ensure the safe transmission of electric energy and prevent current leakage and electric shock accidents, while also reducing external interference and reducing energy consumption.

[0009] Furthermore, the two cuttable insect-proof strips each include an adhesive strip, and the adhesive strip is fixedly bonded to the outer wall of the photovoltaic cable body, a plurality of solid strips are fixedly connected to one side of the outer surface of the adhesive strip, an insect-proof strip body is commonly fixedly connected between two adjacent solid strips, and the insect-proof strip body is fixedly connected to the adhesive strip, the interior of the insect-proof strip body is filled with insect repellent, and the provision of the adhesive strip is conducive to the installation and connection of the cuttable insect-proof strip with the photovoltaic cable body.

[0010] Furthermore, the insect-proof strip body includes a trapezoidal strip, and the trapezoidal strip is fixedly connected to the adhesive strip and the solid strip. A plurality of air holes are provided on both sides of the outer surface of the trapezoidal strip, and microporous filter membranes are fixedly connected to the inner walls on both sides of the trapezoidal strip. The microporous filter membranes are breathable but water-tight, thereby preventing rainwater from entering the interior of the insect-proof strip body and at the same time not affecting the diffusion of the smell of the insect repellent.

[0011] Furthermore, both the outer corrosion-resistant protective layer and the inner corrosion-resistant protective layer are made of silicone rubber, which can be used in the range of -100°C to +250°C and can resist corrosion from chemical media such as acids, alkalis, and oxidants.

[0012] Furthermore, the metal protective layer is made of stainless steel strip, which has good corrosion resistance and is not prone to rust and corrosion.

[0013] Furthermore, the waterproof layer is made of PVC film, which is a polymer synthetic material with good corrosion resistance, waterproofness and insulation properties.

[0014] Beneficial effects of the utility model:

[0015] When the utility model is in use, the waterproof and corrosion-resistant photovoltaic cable has an outer corrosion-resistant protective layer and an inner corrosion-resistant protective layer made of silicone rubber, so that the photovoltaic cable can resist the erosion of chemical media such as acids, alkalis, and oxidants, making it less likely to suffer from problems such as embrittlement and cracking, thereby extending the overall service life; in conjunction with the waterproof layer, water can be prevented from entering the interior of the photovoltaic cable.

[0016] When the utility model is in use, the waterproof and corrosion-resistant photovoltaic cable can prevent termites, rodents and the like from biting and damaging the photovoltaic cable through the metal protective layer and the cuttable anti-insect strip. Once the outer corrosion-resistant protective layer is damaged, the inner corrosion-resistant protective layer cooperates with the waterproof layer, so that the whole still has good waterproof and corrosion-resistant performance.
