Example 1
Please refer to fig. 1-3, in the embodiment of the utility model provides an in, a can generate heat, remove the parallel overhead cable tied in a bundle of resistant type of ice and snow structure, splice bar 7 can be tangent with two fire-retardant sheaths 6, splice bar 7 middle part is rectangle hollow structure, and when splice bar 7 is tangent relation with two fire-retardant sheaths 6, snow is mostly concentrated in the top of splice bar 7 and the outside of fire-retardant sheath 6, and the outside majority of cable does not really contact snow like this, just so can play and resist snow and be less than chilly effect, heat when circular telegram through cable self, with the heat water conservancy diversion to splice bar 7 again on, just can realize the effect of snow melt.
Example 2
Referring to fig. 1-3, the difference from embodiment 1 is: the splice bar 7 can coincide with the centre of a circle connecting wire of two fire-retardant sheaths 6, the middle part of splice bar 7 is rectangle hollow structure, when splice bar 7 lug connection is when the side of two fire-retardant sheaths 6, the function of the protection cable that splice bar 7 also can be the same this moment, avoid snow to pile up on the cable, although contrast splice bar 7 is compared with the tangent structure of two fire-retardant sheaths 6, the area of contact between snow and the cable has increased, but the loss that the heat transfer put to the central point of splice bar 7 still less, have the ablation that helps snow more, thereby reach better snow melt effect.
The utility model discloses a theory of operation is:
the compression coefficient of the outer layer and the inner layer of the first oxygen-free copper conductor 1 and the second oxygen-free copper conductor 2 needs to reach 92% or more during stranding, the cross section of the inner layer and the cross section of the outer layer are required to be circular after stranding and compressing, and the cross section areas of the first oxygen-free copper conductor 1 and the second oxygen-free copper conductor 2 are 120mm respectively 2 And 70mm 2 The flame-retardant sheath 6 is made of a low-smoke halogen-free flame-retardant material, so that toxic and pungent gas is prevented from being generated during combustion, the silicon rubber insulating layer 3 and the connecting ribs 7 are made of weather-resistant high-strength linear low-density polyethylene materials, the low-density polyethylene has good weather resistance, and the weather resistance refers to the resistance to various weather conditions under natural conditions, such as the conditions of material fracture, fading, cracking and the like caused by conventional illumination, high temperature and humidity, so that the aging condition of a series of materials is reduced;
when the connecting ribs 7 are in a tangent relation with the two flame-retardant sheaths 6, most accumulated snow is concentrated above the connecting ribs 7 and on the outer sides of the flame-retardant sheaths 6, most of the outer parts of the cable are not really contacted with the snow, so that the effect of resisting the accumulated snow lower than cold can be achieved, and the heat is guided to the connecting ribs 7 again through the heat generated when the cable is electrified, so that the snow melting effect can be achieved;
when splice bar 7 lug connection is in the side of two fire-retardant sheaths 6, the function of splice bar 7 protection cable that also can be the same this moment avoids snow to pile up on the cable, though compare splice bar 7 and two tangent structures of fire-retardant sheath 6 and compare, the area of contact between snow and the cable has increased, but the loss that the central point of heat transfer to splice bar 7 put still less, has the ablation that helps snow more to reach better snow melt effect.
