Abstract
The utility model discloses a waterproof photovoltaic cable, which comprises a conductor (1), wherein an insulating layer (2) is arranged outside the conductor (1), an inner sheath (3) is arranged outside the insulating layer (2), and an outer sheath (6) is arranged outside the inner sheath (3); along the axial direction of the conductor (1), the outer surface of the inner sheath (3) is provided with a plurality of convex ridges (4) which are uniformly distributed, the convex ridges (4) support an outer sheath (6), a cavity (5) is arranged between every two adjacent convex ridges (4) and between the inner sheath (3) and the outer sheath (6), and water-blocking ointment is arranged in the cavity (5); the utility model discloses a waterproof type photovoltaic cable has the convex ridge structure with the outer extrusion of inner sheath when production, and the unwrapping wire can make the cable take place to twist reverse when filling the oleamen, because of having the convex ridge structure, can make the oleamen that blocks water better adhere to including the sheath surface. Compared with the conventional photovoltaic cable, the waterproof ointment is added, the waterproof performance of the cable is improved, and the applicable working environment and the laying environment range are enlarged.
Description
Technical Field
The utility model relates to a waterproof type photovoltaic cable is used for the connection of each part in solar photovoltaic power generation system.
Background
With the annual expansion of new energy photovoltaic power stations, the demand of new energy photovoltaic cables will also increase year by year. The new energy power generation industry in China is greatly developed, particularly the photovoltaic power generation industry is rapidly increased, in some coastal countries, a photovoltaic power station can be built in coastal areas or even on the sea, so that a photovoltaic cable can be in a state of being in contact with seawater for a long time, the temperature of the coastal areas at night is usually low, the seawater has high corrosivity, the material for a sheath of the photovoltaic cable is usually low-smoke halogen-free polyolefin, and if the tensile strength and the elongation at break of the low-smoke halogen-free polyolefin material are greatly changed after being soaked in water, the long-term service performance of the material is seriously influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a waterproof type photovoltaic cable is provided, this cable has excellent waterproof performance.
In order to solve the technical problem, the waterproof photovoltaic cable comprises a conductor, wherein an insulating layer is arranged outside the conductor, an inner sheath is arranged outside the insulating layer, and an outer sheath is arranged outside the inner sheath; along the axial direction of the conductor, the outer surface of the inner sheath is provided with a plurality of uniformly distributed convex ridges, and the cross section of each convex ridge is preferably rectangular. The convex ridges support the outer sheath, a cavity is formed between the inner sheath and the outer sheath between every two adjacent convex ridges, and water-blocking ointment is arranged in the cavity.
Preferably, the conductor is a tin-plated copper conductor, and the oxidation resistance of the conductor is enhanced. The insulating layer, the inner sheath and the outer sheath are made of low-smoke halogen-free polyolefin, the insulating layer, the inner sheath and the outer sheath are made of materials with the properties of cold resistance, high temperature resistance, high flexibility, oil resistance, moisture resistance, UV resistance, termite resistance and the like, the working temperature can reach (-40 ℃ -125 ℃), and the product can adapt to various environments and provides greater possibility.
The utility model discloses a waterproof type photovoltaic cable has the convex ridge structure with the outer extrusion of inner sheath when production, and the unwrapping wire can make the cable take place to twist reverse when filling the oleamen, because of having the convex ridge structure, can make the oleamen that blocks water better adhere to including the sheath surface. Compared with the conventional photovoltaic cable, the waterproof ointment is added, the waterproof performance of the cable is improved, and the applicable working environment and the laying environment range are enlarged.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a perspective view of the present invention.
Fig. 2 is a plan view of the present invention.
Detailed Description
As shown in fig. 1 and 2, the waterproof photovoltaic cable comprises a conductor, wherein the conductor is a tin-plated copper conductor. The conductor is the insulating layer outward, the insulating layer has the inner sheath outward, the outer oversheath (the sacrificial oversheath structure of increase) that is of inner sheath, the material of insulating layer, inner sheath and oversheath is low smoke and zero halogen polyolefin.
Along the axial direction of the conductor, the outer surface of the inner sheath is provided with a plurality of (four in figures 1 and 2) uniformly distributed ridges, and the cross section of each ridge is rectangular. The convex ridges support the outer sheath, a cavity is arranged between the inner sheath and the outer sheath between two adjacent convex ridges, water-blocking ointment (such as corrosion-resistant water-blocking ointment for an Alice IRIS-150 cable) is arranged in the cavity, and the water-blocking ointment is filled in a coating mode (such as coating by a coating mechanism disclosed in an authorization notice number CN 209804349U).
The utility model discloses increase outer convex ridge structure when sheath production including, have a rectangle convex ridge structure respectively on the upper and lower, left and right sides of die sleeve, the mold core is smooth circular neck structure of taking, and the inner sheath is extruded and is adopted crowded tub of mode, realizes convex ridge structure. The utility model discloses increased the oleamen that blocks water in the middle of inner sheath and oversheath, the unwrapping wire can make the cable take place to twist reverse when filling the oleamen that blocks water, has the convex ridge structure because of the inner sheath, can make the better attached to surface of oleamen, and the oleamen that blocks water has improved cable waterproof performance.
The above-mentioned embodiment does not limit the utility model in any way, and all the technical solutions that adopt the mode of equivalent replacement or equivalent transform to obtain all fall within the protection scope of the utility model.
