Description
Technical field
The utility model relates to a kind of low-voltage cable overhang insulation suspension arrangement, in particular to a kind of low pressure multicore cable is perpendicular
Lifting traction and suspension arrangement to installation.
Background technique
Currently, lifting traction and suspension arrangement that low pressure multicore cable common in market is vertically installed are mostly wire sets
Type, this type suspension arrangement structure and manufacture craft are relatively easy, and principle is locked using the port part of wire sets
The characteristic that hanging ring stress just the more is pulled out the more tight afterwards uses steel wire after phase insulation isolation and encapsulation process are done in multicore cable end
Set, which is coated on outside cable socket and locks net cover open end, comes drawing traction and suspended cables.This type device is due to its knot
Structure and manufacture craft are relatively easy, so at present using more, but there is also many problems.
One, terminal cable length needed for device is longer: the electricity of multicore needed for making such device in prefabricated branch cable engineering
The length requirement of cable terminal at least more than 1.5 meters, cable specification it is bigger needed for length it is longer because it be using cable insulation with
Frictional force three collective effect between adhesive force, insulation between conductor and the frictional force between sheath, wire sets and sheath reaches
To traction and hoisting function, suffered pulling force nearly all acts on protective coverings of cable and insulating layer, if terminal cable length is not
It is sufficient then can occur cable cover(ing) or insulation by pulled out damage even pull-off expose conductor accident, stress cannot be hung for a long time so as not to hair
Outside business.
Two, damage sheath or insulating layer: wire sets open end is locked degree and is difficult to control, and too Song Zeyi occurs net cover and pulls out
De- accident, tightly may then damage restrictive coating very much and insulating layer causes electrical defect hidden danger.
Three, damage overhang insulation sealing: wire sets, which may shrink friction because of tension during drawing lifting, leads
The damage of cable socket insulated enclosure is caused, electrical defect hidden danger even accident is caused.
Four, narrow application range: at the same when also because of its work suffered by pulling force nearly all act on protective coverings of cable and insulating layer,
So not to be suitable for the combination between metal sheath layers and cable core such as flexible mineral insulation type branch cable untight for such device
Product.
To solve the above-mentioned problems, it provides a kind of suitable for various multi-core branch cables, flexible mineral insulation type branch electricity
Traction, lifting and the suspension arrangement of the multiple products such as cable and common multicore cable, the present inventor devise a kind of low pressure multicore
Cable end insulation suspension arrangement, there is this case generation then.
