Embodiment Construction

[0023] Such as figure 1 As shown, the halogen-free flame-retardant power cable described in this embodiment has an outer diameter of 16.9-75 mm, and includes multiple strands of insulated wire cores. The insulated wire cores have a 3+2 core structure, and the insulated wire cores are made of soft The copper conductive wire core made of copper wires and the coated polytetrafluoroethylene composite material halogen-free flame-retardant filling material 20 are formed, and the conductor cross-sectional area of ​​the three main cores 11 is 4-240mm2, and the conductor cross-sectional area of ​​the two sub-cores 12 is The cross-sectional area of ​​the conductor is 2.5-120mm2.

[0024] The insulated wire cores are filled with a halogen-free flame-retardant filling material 20 made of polytetrafluoroethylene composite material, and covered with a water-blocking tape 30, and the outside of the water-blocking tape 30 is an aluminum-plastic composite tape 40. , A shielding layer 50 is us...

Abstract

The invention provides a halogen-free and flame-proof insulating power cable. The halogen-free and flame-proof insulating power cable is that insulating cable cores are of a 3+2 structure and comprises a copper conducting core formed by stranding soft copper wires, and a covered insulating layer; halogen-free and flame-proof filling materials fill between the insulating cable cores and are wrapped through a water blocking tape; a composite belt is arranged at the outside of the water blocking tape; a shielding layer is arranged at the outside of the composite belt; an external halogen-free and flame-proof protecting sleeve is arranged at the outside of the shielding layer; the halogen-free and flame-proof filling materials and the external halogen-free and flame-proof protecting sleeve are prepared from polytetrafluoroethylene composite materials. According to the halogen-free and flame-proof insulating power cable, the water blocking tape, the outer protecting sleeve layer and the like are used as the waterproof parts; meanwhile, the internal filled material is high polymer material added with termite / rat repellents; therefore, the cable is resistant to water and termite and rat, and as a result, the use safety of the cable can be improved.

Description

technical field [0001] The invention relates to a halogen-free flame-retardant insulated power cable, in particular to a power cable using a polytetrafluoroethylene composite material as a halogen-free flame-retardant filling material and a halogen-free flame-retardant outer sheath layer. Background technique [0002] With the continuous and rapid growth of my country's economy, it has provided a huge market prospect for the development of the cable industry. The strong temptation of the Chinese market has made the world focus on the Chinese market. In the short decades of reform and opening up, China The huge production capacity formed by the cable manufacturing industry has impressed the world. With the continuous expansion of industries such as electric power, communications, rail transit, automobiles, and shipbuilding, the demand for wires and cables is also growing rapidly. It can be predicted that the wires and cables industry will have huge development potential in the...
