Abstract
The utility model discloses a kind of steel armored cable, by cable core, insulating barrier and protection steel armour are formed, wherein protect steel armour between cable core and insulating barrier, protection steel armour is made up of more piece sleeve pipe, wherein often joint sleeve pipe one end arranges the groove other end and arranges projection, often in adjacent two joint sleeve pipes, wherein the coated another casing joint of casing joint groove is protruding, groove is separately established at least one shrinkage joint and outer surface thereof and separately establish at least one annular indent, between shrinkage joint width is 0.1-1 centimetre, fastener is established in annular indent, fastener two ends are connected by bolt, fastener length is 9/10 of annular indent girth.The utility model is while guaranteeing available protecting cable; the production that greatly simplify cable protection steel armour is installed and later stage use field-strip; greatly can improve the operating efficiency that cable is produced and laid operation; also effectively can improve the bending property of cable simultaneously, improve the flexibility using and deposit of cable self.
Description
Technical field
The utility model relates to a kind of steel armored cable, belongs to transmission of electricity power field of cable technology.
Background technology
For some high voltage power cables, in order to effectively protect cable core and guarantee its good insulating properties, pull resistance and preferably shock resistance deformability, at present conventional method be cable core with insulate between coated one deck protection steel armour of having elongated straps steel to be entwined, although traditional protection steel armour can play the protective effect of expection, but also greatly limit the bending property of cable simultaneously, simultaneously again because be subject to the restriction of length when the band steel making protection steel armour is produced, multi-ribbon steel is often needed to weld together the needs that could meet cable protection, comparatively difficult when therefore protecting steel armour to make, when carrying out intercepting wireline operation in cable uses simultaneously, protection steel armour dismounting difficulty is larger, general employing handsaw carries out cutting to protection steel armour, under operating efficiency, therefore a kind of novel cable is needed, meeting available protecting cable simultaneously, can conveniently produce and use again, and can effectively improve cable bend performance.
Summary of the invention
The utility model object is just to overcome above-mentioned deficiency, provides a kind of steel armored cable.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of steel armored cable, by cable core, insulating barrier and protection steel armour are formed, wherein protect steel armour between cable core and insulating barrier, described protection steel armour is made up of more piece sleeve pipe, wherein often joint sleeve pipe one end arranges the groove other end and arranges projection, often in adjacent two joint sleeve pipes, wherein the coated another casing joint of casing joint groove is protruding, described groove is separately established at least one shrinkage joint and outer surface thereof and separately establish at least one annular indent, between described shrinkage joint width is 0.1-1 centimetre, fastener is established in described annular indent, described fastener two ends are connected by bolt, described fastener length is 9/10 of annular indent girth.
The utility model is while guaranteeing available protecting cable; the production that greatly simplify cable protection steel armour is installed and later stage use field-strip; greatly can improve the operating efficiency that cable is produced and laid operation; also effectively can improve the bending property of cable simultaneously, improve the flexibility using and deposit of cable self.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
A kind of steel armored cable as shown in Figure 1, by cable core 1, insulating barrier 2 and protection steel armour are formed, wherein protect steel armour between cable core 1 and insulating barrier 2, described protection steel armour is made up of more piece sleeve pipe 3, wherein often joint sleeve pipe 3 one end arranges groove 4 other end and arranges protruding 5, often in adjacent two joint sleeve pipes 3, wherein coated another casing joint 3 projection 5 of casing joint 3 groove 4, described groove 4 is separately established at least one shrinkage joint 6 and outer surface thereof and separately establish at least one annular indent 7, between described shrinkage joint 6 width is 0.1-1 centimetre, fastener 8 is established in described annular indent 7, described fastener 8 two ends are connected by bolt 9, described fastener 8 length is 9/10 of annular indent 7 girth.
