Problems solved by technology

In actual use, this kind of ant-proof cable has the following defects: 1. The sheath material is expensive, which is 8 to 15 times that of ordinary cable sheath materials; 2. The sheath material is not easy to form, and the sheath of the produced cable is qualified The efficiency is extremely low, and the sheath material is extremely sensitive to foreign matter, requiring special machinery and equipment, and the investment in equipment is high. After the production is stopped, the screw cavity and the screw must be cleaned completely, which takes a long time to produce and the production speed is slow; 3. The sheath material is relatively thin, and the sheath is easily damaged during construction, and it is extremely difficult to repair

Abstract

The invention belongs to the field of electric power and cable technology, and in particular relates to an ant-proof cable, which includes a cable core in the prior art, and is characterized in that the cable core has an outer sheath layer, and spirals along the outside of the cable core. It is coated with a low-temperature heating element, and the heating temperature of the low-temperature heating element is 35-60° C.; the low-temperature heating element is located in the outer sheath layer or between the outer sheath layer and the cable core. The invention also discloses the manufacturing method of the anti-ant cable and the anti-ant method. The anti-ant cable of the present invention has the following main beneficial effects: low comprehensive cost, easy construction, more reliable quality during construction, and easy manufacture; the anti-ant method of the present invention is simple and easy to grasp.

Description

Technical field [0001] The present invention is the field of power and cable technology, especially in an ant cable and its antitripathy method. Background technique [0002] As one of the pests, termites often erode with wood, cables, etc. After the termite eats cable protectives, the cable conductive or signal transmission part is exposed, which not only causes safety to suffer, but also affects the normal use of the cables, but also affects the normal use of the cables.And life.To this end, in the ant -region, users often put forward the requirements for anti -ants. Among the existing technologies, the cable anti -anticida is mainly implemented by preventing ant sets.The Standard of the Communication Industry of the People's Republic of China YD / T 1020-1999 "Technical Requirements for Communication Optical Cables, Cable Anti-Termit Outside Sheets" stipulates that the anthrom protective materials are polyamide 11, polyamide 12 or polyamide 1010, and the thickness is 0.3~ 0.5mm....
