Abstract

The invention discloses an electric cable, and relates to the field of electricity facility. Raw materials of the sheath tube of the cable comprise, by weight, 85 parts of polyolefin, 3 parts of plant ash, 2 parts of gum, 0.6 parts of a silane coupling agent, 1.5 parts of stearic acid, 0.7 parts of white carbon black, and 4 parts of electrolytic zinc acid leaching residue. The tensile strength of the cable sheath tube is higher than 26 MPa. The breaking elongation of the cable sheath tube is higher than 750%. The oxygen index of the cable sheath tube is higher than 36. The flame retarding performance of the cable sheath tube reaches the A level. The cable sheath tube also has significant characteristics of high strength and high flame retarding performance. Also, plant ash and electrolytic zinc acid leaching residue are recycled, such that environment pollution is reduced, and production cost is reduced. The electric cable has significant economic and environmental benefits.

Description

[0001] This application is a divisional application of Chinese Patent Application No.: 2014101586477; Invention Name: High Strength High Flame Retardancy Cable; Application Date: 2014.04.21. technical field [0002] The invention relates to the field of electric facilities, in particular to a cable with high strength and high flame retardancy. Background technique [0003] With the gradual acceleration of the urbanization process, urban planning is becoming more and more modern. In the process of urban construction, cable entry into the ground has become the minimum construction requirement. At the same time, in the process of urban transformation, it is also necessary to put various cables erected in the air into the ground. At present, the construction of cables into the ground often adopts non-excavation technology. This construction method has the advantages of no impact on traffic, little damage to the stratum structure, and short cycle. , has the performance: the ca...
