[0002] With the continuous development of the power industry, the demand market for cables is also expanding. A cable is an electrical energy or signal transmission device, usually composed of several or several groups of conductors. There are many types, including power cables, control cables, compensating cables, signal cables, and computer cables. In order to protect the performance of the cable, the surface of the cable is often covered with a cable protective sleeve.
[0003] Existing outdoor cable protective sleeves have poor cold resistance. In cold weather, the cables are prone to becoming brittle and damaged, reducing their service life. Utility Model Content
[0004] The purpose of this invention is to provide a frost-resistant outdoor cable protection sleeve to solve the problem that an existing frost-resistant outdoor cable protection sleeve is easily damaged by freezing.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a frost-resistant outdoor cable protective sleeve, comprising a protective sleeve body, wherein the protective sleeve body is installed on the outside of the cable body, and a flame-retardant structure and an anti-freeze structure are sequentially arranged on the inner side of the protective sleeve body. The flame-retardant structure and the anti-freeze structure can improve the flame-retardant and anti-freeze performance of the cable body and increase its service life. The anti-freeze structure includes an inner protective sleeve, an outer protective sleeve and a heating wire. The inner protective sleeve is installed on the outer surface of the cable body, and a heating wire is installed on the outer surface of the inner protective sleeve, and an outer protective sleeve is installed on the outer surface of the heating wire. Both ends of the protective sleeve body are provided with fixing structures, which can improve the stability of the installation of the protective sleeve body.
[0006] Preferably, the fixing structure includes an elastic pressure plate, a fixing ring, and a screw sleeve. The screw sleeve is installed at both ends of the protective sleeve body. An elastic pressure plate is evenly installed at one end of the screw sleeve, and a fixing ring is threaded to the outer side of the screw sleeve.
[0007] Preferably, the elastic pressure plate is distributed in a ring at one end of the threaded sleeve.
[0008] Preferably, sealing gaskets are installed at both ends inside the protective sleeve body.
[0009] Preferably, the flame-retardant structure includes an outer flame-retardant layer, an antifreeze layer, and an inner flame-retardant layer. The outer flame-retardant layer is installed on the inner side of the protective sleeve body, an antifreeze layer is installed on the inner side of the outer flame-retardant layer, and an inner flame-retardant layer is installed on the inner side of the antifreeze layer.
[0010] Preferably, the inner protective sleeve is a heat-conducting layer, and the outer protective sleeve is a heat-insulating layer.
[0011] Preferably, the heating wire has a spiral structure.
[0012] The advantages of the antifreeze outdoor cable protective sleeve provided by this utility model are as follows:
[0013] With its antifreeze structure, the inner protective sleeve can transfer the heat from the heating wire to the cable body, thereby raising its temperature and preventing damage caused by the cable body becoming brittle and hard due to cold, thus extending the cable's service life.
[0014] Through the flame-retardant structure, the outer flame-retardant layer and the inner flame-retardant layer can play a certain flame-retardant role, enhance the fire resistance of the protective sleeve body, and improve the protection effect on the cable body. The antifreeze layer can enhance the cold resistance of the protective sleeve body and further improve the antifreeze effect of the cable body.
[0015] By using the fixed structure, rotating the fixed ring pushes the elastic pressure plate into contact with the cable body, which can play a certain role in fixing the protective sleeve body and improving its installation stability. The sealing gasket can enhance the sealing between the protective sleeve body and the cable body. Attached Figure Description
