Technical field
The utility model relates to a kind of lead gold utensil that continues, and particularly a kind of preformed lead splicing sleeve strengthens connection device.
Background technology
Using the very huge splicing sleeve of number on the power overhead network, adopting hydraulic pressure or pincers pressure technology, layering continues respectively to the steel core part and the aluminium lamination part of steel reinforced aluminium conductor.Its drawback is: 1. Shi Gong handshaking procedure more complicated, need special crimping apparatus, and effect is installed is subjected to operating personnel's artificial factor to a great extent, easily cause physical damnification (mechanical damage), cause taking place lead strand crack conditions lead; 2. power circuit service life often requires to surpass 30 years, and run duration forms thermal cycle owing to the instability of circuit operating load produces the temperature phenomenon of lifting repeatedly, makes adapting electric voltage increase, thereby has increased line loss; The mechanical strength that continues simultaneously descends, and the safe operation of transmission line is constituted a threat to.
The utility model content
The utility model is at above problem, provide a kind of and can solve the deficiency of aforementioned crimp type splicing sleeve existence in service effectively, both strengthened the current capacity of splicing sleeve, greatly reduce the resistance and the loss at the place that continues again, can also strengthen simultaneously the intensity that continues of splicing sleeve, make its breakdown strength that is not less than lead, and the higher efficient heavier-duty lead connection device of installation effectiveness.
The technical solution of the utility model is: comprise aluminium hydraulic pressed connecting pipe and reinforcement preformed armor rods, described aluminium hydraulic pressed connecting pipe docks described lead, described reinforcement preformed armor rods twines, wraps outside lead and aluminium hydraulic pressed connecting pipe, and the described reinforcement preformed armor rods of 2-5 root is single to connect as one side by side, coiling constitutes preformed son bundle twist again; The rotary orientation of described preformed son bundle is identical with described lead rotation direction, and the 1.5-10 that described preformed sub-Shu Changdu is an aluminium hydraulic pressed connecting pipe times, two parts length that described preformed son bundle two ends exceed aluminium hydraulic pressed connecting pipe is identical; The screw pitch one of the corresponding aluminium hydraulic pressed connecting pipe part of described preformed son bundle is consistent with aluminium hydraulic pressed connecting pipe length, and described two screw pitches two that exceed part are the 5-50% of screw pitch one.
Described lead is a steel reinforced aluminium conductor, also is provided with the splicing sleeve that is used for the crimping steel core in the described aluminium hydraulic pressed connecting pipe.
The utility model employing individual layer is preformed, the preformed son bundle structure of many bunchys arranged side by side, and middle part and aluminium hydraulic pressed connecting pipe contact site make its pitch length close with aluminium hydraulic pressed connecting pipe length through stranded, are convenient to install.The prefabricated shaping of preformed armor rods has conduction sand behind its inner surface additional, to improve electric conductivity; Preformed armor rods adopts the aluminum-alloy wire manufacturing, with convenience and the high conduction performance that utilizes its processing; Preformed armor rods is a multifibres state arranged side by side during payment, twines with respect to monofilament, and install and use at more convenient scene, can allow preformed sub-synnema be wrapped in aluminium hydraulic pressed connecting pipe and lead outside equably.In order to improve anti-corona ability, special processing also can be carried out in the termination of preformed armor rods, such as being made into smooth dome-type or Duckbill type.

Embodiment
The utility model is shown in Fig. 1-7: comprise aluminium hydraulic pressed connecting pipe 1 and reinforcement preformed armor rods, described aluminium hydraulic pressed connecting pipe 1 is with described lead 3 butt joints, described reinforcement preformed armor rods twines, wraps outside lead 3 and aluminium hydraulic pressed connecting pipe 1, and the described reinforcement preformed armor rods of 2-5 root connects as one side by side, coiling constitutes preformed son bundle 2 twist again; The rotary orientation of described preformed son bundle 2 is identical with described lead 3 rotation directions, and described preformed son bundle 2 length are 1.5-3 times of aluminium hydraulic pressed connecting pipe 1, and two parts length that described preformed son bundle 2 two ends exceed aluminium hydraulic pressed connecting pipe 1 is identical; Screw pitch one l of described preformed son bundle 2 corresponding aluminium hydraulic pressed connecting pipe 1 parts
