Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing:

[0018] The present invention is a high electrical conductivity, comprehensive radial water resistance / water resistance, weather resistance, and has the characteristics of severe cold resistance, low temperature flexibility, good electrical performance, high tensile strength and long service life. Power cables for power distribution systems. Its specific structure is as figure 2 As shown, the conductor unit 1 is at its center, and the conductor unit 1 is covered with a conductor shielding layer 2, an insulating layer 3, an insulating shielding layer 4, a semiconducting resistance water buffer layer 5, and a corrugated aluminum sheath 6 in sequence from the inside to the outside. and outer sheath7. The material of the insulating layer 3 is preferably cross-linked polyethylene, and the material of the outer sheath 7 is preferably an environmentally friendly flame-retardant ...

Abstract

The invention discloses a large-section milliken-conductor comprehensive water-retaining crosslinking electric cable which is characterized in that a conductor unit (1) is arranged at the center of the electric cable, a conductor shielding layer (2), an insulation layer (3), an insulation shielding layer (4), a semi-conductive water-retaining buffer belt layer (5), a corrugated aluminum sheath (6) and an outer sheath (7) are sequentially coated on the conductor unit (1) from inside to outside. The large-section milliken-conductor comprehensive water-retaining crosslinking electric cable is high in conductivity, comprehensive in radial water-retaining / waterproofness and weather fastness and has the advantages of resistance to low temperature, low-temperature flexibility, good electric performance, high tensile resistance and long service life and the like.

Description

technical field [0001] The invention relates to a cable for power transmission and distribution, in particular to a comprehensive water-blocking cross-linked power cable with a large cross-section split conductor. Background technique [0002] In recent years, with the development of the national economy, the power consumption has increased sharply, and the demand for large-section and large-capacity transmission cables has increased year by year. Domestic 630mm 2 The quality of cross-linked cables and below is still stable, but the 800mm 2 Due to equipment, process equipment, process technology and other reasons, the conductive core of cross-linked cables is difficult to produce and the quality is unstable. 800mm 2 For conductors with large cross-sections and above, the transmission capacity does not increase linearly with the increase of the conductor cross-section. The reason for this phenomenon is the influence of "skin effect" and "proximity effect". In order to mi...
