Abstract
The utility model relates to a high-electrical performance weatherproof insulating overhead cable with not higher than 20kV, which is extruded and coated with an internal insulating layer and an external insulating layer on a conductor in a double-layer co-extrusion and silane crosslinking mode. The conductor adopts a round compacting copper wire stranding structure. The internal insulating layer is made of semicondcutive shielding materials. The external insulating material is made of high-electrical performance weatherproof cross-linked polyethylene insulating materials. The high-electrical performance weatherproof insulating overhead cable has the advantages of good electrical performance, long service life, fast color and no cracking when being erected overhead, and no descending on insulation performance, and capability of running outdoors safely for a long time.
Description
Technical field
The utility model relates to a kind of 20kV and the weather-proof insulated aerial cable of following high electrical performance, belongs to technical field of electric wires and cables.
Background technology
The overhead distribution net is the important component part of urban and rural power grids, and it extends in all direction, and is getting in touch huge numbers of families intricately, and its amount of power supply is about 60% of a power system power supply amount.Along with The development in society and economy, whole society's power consumption increases fast, and especially in part densely populated, economically developed central area or infant industry garden, load density has reached 15～20MW/km
2, load density at a specified future date will reach 30～50MW/km
2Design a kind of high performance 20kV and following aerial cable, China's urban and rural power grids electric utility development is had positive social effect.
Summary of the invention
The purpose of this utility model provides a kind of good electric property, long service life, be erected at colour-fast when aerial, do not ftracture, insulation property do not descend, can be at the 20kV and the weather-proof insulated aerial cable of following high electrical performance of outdoor long-term safety operation.
The technical solution of the utility model is: a kind of 20kV and the weather-proof insulated aerial cable of following high electrical performance, it is that the mode with double-layer coextrusion, crosslinked with silicane extrudes inner insulating layer and external insulation layer on conductor.
Described conductor adopts circle to press the copper cash lay configuration, and its performance meets the GB/T3956-2008 national Specification.
Described inner insulating layer adopts semi-conductive shielding material, and its average thickness is 0.6mm, and minimum thickness is 0.50mm.
Described external insulation layer adopts the weather-proof crosslinked polyethylene insulation material of high electrical performance, and its thickness is 3.4mm～5.5mm.This external insulation layer can guarantee aerial cable be laid in colour-fast when outdoor, do not ftracture, insulation property do not descend.
The utility model is a kind of 20kV and the weather-proof insulated aerial cable of following high electrical performance, inner insulating layer and external insulation layer adopt double-layer coextrusion, the disposable insulating barrier of producing of crosslinked with silicane mode during production, and adopt advanced Totally closed production technology and selected technology such as dust separation for use, there is not impurity to bring insulating barrier in the time of guaranteeing the cleannes of insulating material so effectively and can guarantee production.Make this cable have higher electric property and long useful life.
The utility model has the advantages that provides a kind of good electric property, long service life, be erected at colour-fast when aerial, do not ftracture, insulation property do not descend, can be at the 20kV and the weather-proof insulated aerial cable of following high electrical performance of outdoor long-term safety operation.
