Description
Technical field
The utility model relates to extra high voltage network connection construction technical fields, more particularly, to a kind of EHV transmission
Route steel-cored aluminium strand splicing sleeve.
Background technique
At present；The intermediate connection and terminal connection of extra high voltage network Large-diameter Steel core aluminum stranded wire；Strand core connection
It is all made of steel pipe to be attached with locking press machine, outer layer aluminum stranded conductor is attached using the effective locking press machine of aluminium set, steel core
Aluminum stranded conductor outer layer crimps position end with aluminum casing, often flattens contact layer aluminum conductor, due to long-term wind vibration, bending,
The stranded phenomenon of damage location aluminum conductor is flattened to happen occasionally.
Summary of the invention
The purpose of this utility model is to be directed to；Extra high voltage network Large-diameter Steel core aluminum stranded wire, aluminum casing connection at present
What is generated is easy stranded status, and a kind of extra high voltage network steel-cored aluminium strand splicing sleeve provided.
Technical solution adopted by the utility model to solve its technical problems is；Using aluminum casing, aluminum casing both ends inner hole
Tapered horn mouth is made, inside one section is processed the hole that can be inserted into teflon sleeve, aluminum casing, teflon sleeve
Internal orifice dimension it is consistent, which produces according to the outside diameter schedule of steel-cored aluminium strand and corresponding various line footpath specifications is matched
The series of products of conjunction.
When the utility model is used；The utility model is inserted in the one end for the steel-cored aluminium strand to be connected, exposes one section
Distance, according to the half of the length of strand core aluminium hydraulic pressed connecting pipe, cut the external aluminum stranded conductor part of steel-cored aluminium strand, reservation steel strand wires
The part of strand core must not be injured when core, cutting, the other end steel-cored aluminium strand with connection equally operates, later with above
It the strand core at both ends, is inserted into the hole of strand core aluminium hydraulic pressed connecting pipe, with locking press machine by authorized pressure, by both ends steel strand wires
Core links together, the utility model is then moved to the steel-cored aluminium strand of both ends docking, to both ends apart from consistent position,
It is gradually crimped with locking press machine by authorized pressure, by 1 both ends of aluminum casing, avoids center strand core aluminium hydraulic pressed connecting pipe connecting portion.
After the completion of the utility model connection；Both ends steel-cored aluminium strand and strand core are closely joined together, due to aluminium set
Pipe both ends inner hole makes tapered aluminum casing horn mouth, due also to teflon sleeve is inserted at aluminum casing both ends；Aluminum stranded conductor
It crimps position with aluminum casing to be closely joined together, teflon sleeve crimping position closely closely connects with steel-cored aluminium strand
It is connected together, due to the flexible nature of teflon sleeve, the damage deformed will not be caused to steel-cored aluminium strand, when the work of wind
With making when steel-cored aluminium strand vibration bending, also to cause to damage to steel-cored aluminium strand, steel-cored aluminium strand company is effectively prevented
It connects and locates the generation of stranded phenomenon transmission line of electricity is effectively guaranteed so substantially prolonging the service life of steel-cored aluminium strand
Safe operation.
The utility model has the beneficial effects that: since the both ends of the utility model insert poly- four with flexible effect
Vinyl fluoride casing, due also to aluminum casing both ends horn mouth so that the locking pressure to aluminum stranded conductor is gradually reduced to outside, steel
The aluminum conductor of core aluminum stranded wire and aluminium set tube end does not have mechanical damage, to reduce a possibility that aluminum conductor is stranded, this is practical
The novel terminal connection that can be applicable to steel-cored aluminium strand.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Attached drawing 1 is the outside drawing that the utility model connection is completed.
Attached drawing 2 is the sectional structure chart of the utility model one end.
Attached drawing 3 is the sectional structure chart that one end crimping of the utility model is completed.
In figure: 1, aluminum casing, 2, teflon sleeve, 3, steel-cored aluminium strand, 4, crimping pit, 5, strand core, 6,
Strand core aluminium hydraulic pressed connecting pipe, 7, aluminum casing horn mouth, 8, teflon sleeve crimping position, 9, aluminum stranded conductor and aluminum casing pressure contact portion
Position.
Specific embodiment
The utility model includes in attached drawing: the teflon sleeve 2 being inserted into respectively by aluminum casing 1 and both ends is formed,
1 inward at both ends end of aluminum casing production aluminum casing horn mouth 7 and inside one section of processing can be inserted into the hole of teflon sleeve,
Aluminum casing 1, the internal diameter of teflon sleeve 2 are consistent, according to the outside diameter schedule of steel-cored aluminium strand 3, produce and corresponding each
The series of products of kind line footpath specification cooperation.
When the utility model is used；The utility model is inserted in the one end for the steel-cored aluminium strand 3 to be connected, exposes one section
Distance, according to the half of the length of strand core aluminium hydraulic pressed connecting pipe 6, cut the external aluminum stranded conductor part of steel-cored aluminium strand 3, retain steel strand
The part that strand core 5 must not be injured when core 5, cutting is equally operated with the other end steel-cored aluminium strand 3 of connection, with above,
Later the strand core 5 at both ends, be inserted into the hole of strand core aluminium hydraulic pressed connecting pipe 6, with locking press machine by authorized pressure, by both ends
Strand core 5 links together, and the utility model is then moved to the steel-cored aluminium strand 3 of both ends docking, to both ends distance one
The position of cause is gradually crimped by authorized pressure, by 1 both ends of aluminum casing with locking press machine, avoids center strand core aluminium hydraulic pressed connecting pipe 6
Connecting portion.
After the completion of the utility model connection；Both ends steel-cored aluminium strand 3 and strand core 5 are closely joined together, due to aluminium
1 both ends inner hole of casing makes tapered aluminum casing horn mouth 7, due also to teflon sleeve 2 is inserted at 1 both ends of aluminum casing；
Aluminum stranded conductor crimps position 9 with aluminum casing and is closely joined together, teflon sleeve crimp position 8, closely with steel-core-aluminium twist
Line 3 is closely joined together, and due to the flexible nature of teflon sleeve 2, the damage deformed will not be caused to steel-cored aluminium strand 3
Wound when wind action makes the vibration bending of steel-cored aluminium strand 3, also will not be caused to damage, be effectively prevented to steel-cored aluminium strand 3
