Abstract
The invention relates to a copper and aluminum connection structure with a flame retardant insulation bush. In the connection structure, cold welding and pressure welding manners are simultaneously adopted for fixedly connecting a copper conductor joint section of a copper conductor and an aluminum conductor joint section of an aluminum conductor into a copper and aluminum conductor joint section; the copper and aluminum conductor joint section and the peripheries of the copper conductor joint section and the aluminum conductor joint section which are adjacent to the copper and aluminum conductor joint section are coated by heat-shrinkable insulation bushes with a good flame retardant property; and the tension resistance strength of the copper and aluminum conductor joint section is not less that 200 N. The copper and aluminum connection structure with the flame retardant insulation bush can ensure that the two different metal conductors can well contact, have the characteristics of good strength and good insulation property, and can not be broken, carbonized and burnt easily in operation for a long time.
Description
Technical field
The present invention relates to a kind of copper aluminium syndeton, particularly a kind of copper aluminium syndeton with fire retardant insulating sleeve pipe.Belong to technical field of electric wires and cables.
Background technology
In China's urban and rural power grids house lead in electric line, what adopt being connected of copper conductor and aluminum conductor is canoe, after promptly twining by hand with two kinds of different plain conductors, wraps insulating tape or autoadhesion adhesive tape more outside.There is following point in actual use in this traditional syndeton: (1) can not guarantee the good contact between two kinds of different metal leads.(2) because lead is repeatedly crooked when twining, reduce intensity, can cause the joint broken string behind the long-play.(3) insulating tape and autoadhesion adhesive tape are to be made by fiber and colloidal materials, when connecting the conductor temperature rising, and easily carbonization, easily cause burning when meeting naked light or reaching uniform temperature, if outdoor application very easily loses insulating effect through exposing to the sun and rain, cause electric leakage, Danger Electric shock risk.
Summary of the invention
The purpose of this invention is to provide a kind of copper aluminium syndeton with fire retardant insulating sleeve pipe, this copper aluminium syndeton can guarantee that the good contact between two kinds of different metal leads has the advantage that intensity is good, also can not break, be difficult for carbonization, nonflammable and good insulation preformance through long-play again.
Technical scheme of the present invention is: a kind of copper aluminium syndeton with fire retardant insulating sleeve pipe.Copper wire lead section to copper conductor adopts the cold welding welding to become copper aluminum conductor junction with crimping dual mode Joint with the aluminum conductor junction of aluminum conductor simultaneously.All coat the good heat shrinkage insulation sleeve pipe of a fire resistance at copper aluminum conductor junction and copper wire lead place and the periphery, aluminum conductor joint adjacent with copper aluminum conductor junction.
The tensile strength of described copper aluminum conductor junction should be not less than 200N.
Described copper conductor adopts the soft circular copper wire of TR type, and aluminum conductor adopts the round firmly aluminum steel of LY9 type.
Described insulating sleeve is to make on its softening copper conductor connecting line that closely is coated on copper aluminum conductor junction and two ends thereof and the aluminum conductor connecting line with the air-heater heating earlier.
Advantage of the present invention has provided a kind of copper aluminium syndeton with fire retardant insulating sleeve pipe, and this copper aluminium syndeton can guarantee that the good contact between two kinds of different metal leads has the advantage that intensity is good, also can not break, be difficult for carbonization, nonflammable and good insulation preformance through long-play again.
