Problems solved by technology

For wireless signal transmission towers and their signal transmitters, there is also the problem of ice condensation. Once ice condensation occurs, the signal transmission will be affected at the slightest, and the tower will collapse if it is severe.
There is also the problem of icing on the transmission lines, transmission poles and tension lines of electrified railways. Once icing occurs, it will affect the power supply at least, and cause the wires to break if it is serious.
[0003] These natural disasters endanger the national lifeline projects, which will not only cause huge economic losses, but also bring great inconvenience to people's lives, and even endanger people's lives in severe cases.

Embodiment 1

[0034] like figure 1 The shown anti-icing cable of the present invention includes a cable 1 and an anti-condensation sleeve 2 provided on its surface. There is a gap between the inner surface of the anti-condensation sleeve 2 and the outer surface of the cable 1, and the two can rotate relative to each other. Among them, the cable 1 is a signal line of an outdoor empty frame, and the anti-condensation sleeve 2 is made of polyurethane material with low thermal conductivity and low density, and its cross section is a hollow closed circular structure. In order to prevent heat exchange and reduce the actual contact area between the anti-condensation sleeve and the cable, some granular protrusions 3 are arranged at intervals on the inner surface where the anti-condensation sleeve contacts the cable.

[0035]Due to the installation of the anti-condensation sleeve 2, the heat exchange between the cable and the outside is greatly reduced, and when rainwater falls directly on the cable...

Embodiment 2

[0037] like figure 2 The shown anti-icing cable of the present invention is different from the first embodiment in that the cable 1 is a high-voltage electric wire with an empty frame in the field, and is composed of multiple metal wire cores. The anti-condensation sleeve 2 is made of foaming material with low thermal conductivity, and adopts an internal structure that is gradually denser from the center to both sides to improve its heat insulation effect and keep the surface smooth; in order to improve the water repellency of the product, the anti-condensation sleeve 2 is also provided with a water-repellent film 4 on the surface. Since the shape of the anti-condensation sleeve is a smooth and round tube, the blind area for storing rain and snow for multi-strand cables is eliminated; the application of heat insulation materials and water-repellent materials reduces the freezing speed and release of raindrops when they meet the anti-condensation sleeve The latent heat speed ...

Embodiment 3

[0041] like image 3 The shown anti-icing cable of the present invention includes the cable and the anti-condensation sleeve provided outside the cable. The cable 1 is an empty high-voltage electric wire in the field, and is composed of multiple strands of metal wire cores. The anti-condensation sleeve is composed of a PVC substrate 10 and a water-repellent film 4 arranged on its surface, and the water-repellent film is Teflon. In order to facilitate the sliding of rain and snow, the anti-condensation sleeve is set in a drop shape with a hollow cross section. In order to ensure that the cables can dissipate heat effectively in high temperature weather, a plurality of through holes 6 are provided at the lower part of the anti-condensation sleeve. In order to prevent unfavorable phenomena such as water ingress in the anti-condensation sleeve caused by turning the side with the through hole to the top of the cable, a counterweight 7 is set on the drop-shaped tip of the anti-con...

Abstract

The invention relates to an anti-ice condensation cable which is suitable for frozen and rainy rough weather and an auxiliary facility which is matched with the anti-ice condensation cable and has an anti-ice condensation property. According to an anti-ice condensation field metal tower body, anti-condensation elements are arranged on the surface of a part with high ice condensation possibility on the tower body, and are arranged on the surfaces of a rod and a post which form the tower body in a buckled, sleeved, coated or adhered mode. By a method for arranging anti-condensation sleeves or the anti-condensation elements on the part with high ice condensation possibility on the tower body, ice condensation on the surface of the cable is effectively prevented, heat exchange between the cable and an external environment is greatly reduced, and the phenomenon of ice condensation caused by heat absorption due to direct contact between rainwater and the tower body is effectively prevented.

Description

technical field [0001] The invention relates to an anti-icing electric wire or cable suitable for freezing and rainy weather, and auxiliary facilities with anti-icing characteristics used together with the electric wire or cable. Background technique [0002] Since China has a vast land area and spans multiple temperature zones, the temperature varies greatly from province to province, and rain and snow disasters occur from time to time. Judging from the 2008 rain, snow and freezing disasters in southern China, when the air temperature near the ground is below zero and the air at high altitude is relatively warm and freezing rain or snow falls, the raindrops or rain and snow hit the cold power lines, iron towers or When insulating bottles, because these objects are good conductors of heat, they can quickly conduct the heat in the rainwater and release it to the surrounding cold air, or in other words, quickly guide the coldness of the object itself and the coldness in the su...
