Abstract
The utility model provides a kind of glass insulating sleeve, belongs to electric power project engineering field.It solves the problem of combination properties such as the fire prevention of existing cable sleeve pipe, waterproof are not good.This glass insulating sleeve, including acrylic resin outer layer and glass layer, glass layer interlocks to knit to connect by many fiberglass flame warp thread and Duo Gen fiberglass flame weft yarns to be formed, the first layer of silica gel is provided with the internal face of glass layer, the second layer of silica gel is provided with the outside wall surface of glass layer, PUR tack coat is provided between the second layer of silica gel and acrylic resin outer layer.It is by setting glass layer and layer of silica gel so that sleeve pipe has preferably fire prevention, waterproof and insulate performance, while again by setting acrylic resin outer layer to improve the overall construction intensity of sleeve pipe, it is to avoid the fail in compression due to glass layer.
Description
Technical field
The utility model belongs to electric power project engineering field, is related to a kind of cable sleeve, particularly a kind of glass insulation sleeve
Pipe.
Background technology
Cable sleeve, is a kind of new casing material promoted the use of in power engineering, for the direct-burried under runway and
Need not plus concrete cover, can accelerate cable work construction progress, thus need to have higher structural strength and rigidity,
Also need to possess fire prevention, waterproof and insulate simultaneously, existing sleeve pipe is made up of PVC or PP mostly, and combination property is not good, also not
The diverse requirements of power engineering can be met.
The content of the invention
The purpose of this utility model is there is above mentioned problem for existing technology, it is proposed that a kind of glass insulating sleeve,
It has preferably insulation, waterproof and fire protecting performance.
The purpose of this utility model can be realized by following technical proposal：A kind of glass insulating sleeve, it is characterised in that
Including acrylic resin outer layer and glass layer, the glass layer is prevented fires by many fiberglass flame warp thread and Duo Gen
Glass fiber weft, which interlocks to knit to connect, to be formed, and the first layer of silica gel, glass layer are provided with the internal face of the glass layer
Outside wall surface on be provided with the second layer of silica gel, be provided between second layer of silica gel and acrylic resin outer layer PUR bonding
Layer.
It is that good insulating, heat resistance be strong, corrosion resistance is good that the glass layer of this sleeve pipe, which has, and mechanical strength height etc. is excellent
Point, layer of silica gel is set on the inside and outside wall of glass layer simultaneously by dipping process, and technique is simple, easy to operate, and enters
One step has waterproof fireproofing and insulating properties.By the outermost layer of sleeve pipe be set to polypropylene resin layer can cause sleeve pipe have compared with
High structural strength, it is to avoid crushing.Both it had been avoided that staggeredly branch knitted the glass layer connect and scratch is caused to electric wire, cable,
It is easy to again by PUR and acrylic resin outer layer phase adhesion simultaneously, tightness is good.
In above-mentioned glass insulating sleeve, the fiberglass flame Warp Tension Test is often 6~9 warp thread of circulation.
In above-mentioned glass insulating sleeve, the fiberglass flame weft yarn arrangement is often 6~9 weft yarns of circulation.
In above-mentioned glass insulating sleeve, the weft yarn period and fiberglass flame of the fiberglass flame weft yarn
The warp thread period of warp thread is consistent.
In above-mentioned glass insulating sleeve, the fiberglass flame warp thread and fiberglass flame weft yarn are by 500
~600 a diameter of 6 μm~10 μm of glass fiber single filament boundling is formed.
In above-mentioned glass insulating sleeve, the thickness of first layer of silica gel and the thickness of the second layer of silica gel are consistent.
In above-mentioned glass insulating sleeve, the thickness proportion of the polypropylene resin layer and glass layer is 2:1~
3：1.Thicker polypropylene resin layer can improve the structural strength of sleeve pipe, reduce the fragility influence of glass layer.
In above-mentioned glass insulating sleeve, the outside of the acrylic resin outer layer is also arranged with silica gel foaming tube.Silicon
Glue foaming tube can further improve the fire prevention of this insulating sleeve, waterproof and insulate performance.
Compared with prior art, the utility model has the following advantages that：
1st, this insulating sleeve is by setting glass layer and layer of silica gel, with preferable fire prevention, waterproof and insulate performance.
2nd, this insulating sleeve is by setting acrylic resin outer layer, and acrylic resin outer layer thickness relative to glass fibers
Layer is tieed up bigger, with higher structural strength, in addition by setting silica gel foaming tube, additionally it is possible to further avoid this insulating sleeve
When in use by crushing.
