Abstract
The utility model relates to an insulator crossarm, which is composed of hardware fittings 1 and 2, a high-strength insulating core rod and an insulating umbrella skirt. The opposite directions of the two hardware fittings are respectively provided with a cylindrical hole, and the core rod tightly matches and seals with the cylindrical holes after inserting into the cylindrical holes. The center of the insulating umbrella skirt is provided with a cavity which can be sheathed on the core rod to tightly match with the core rod. The front end and the upper side of the hardware fitting 1 are respectively provided with a semi-circular slot which is used for embedding the conducting wires of a distribution network. A flat handle of the hardware fitting 2 is provided with a bolt hole which enables the cross arm to be fixed on a wire pole. The insulator crossarm has the advantages of light weight, high strength, stretch resistance, fracture resistance and pollution resistance, and can completely satisfy the requirement of supporting the conducting wires with continuously enlarged cross-sectional areas.
Description
The utility model relates to the insulation stent of a kind of 6KV of being applied to, 10KV power matching network aerial condutor.
In decades, the used insulation stent of 10KV distribution trolley line generally adopts porcelain pole arm---and the porcelain rod supports.
Along with the development of national economy, the industry and the rapid growth of city need for electricity, 10KV distribution overhead wire passes through big small city, spreads all over streets and lanes, and sectional area of wire increases year by year, has also increased the mechanical loading of support porcelain rod simultaneously.Yet because raw materials for production and production technology have determined the mechanical bending resistance load of used porcelain rod can not meet the demands, the fracture of porcelain rod causes accident, causes the situation of power failure to take place again and again.For solving this contradiction, two cross-arms have been adopted in the 10KV distribution---and two porcelain rods guarantee the distribution safe operation to increase bending resistance.
In view of the defective that porcelain pole arm exists is supported in above-mentioned 10KV distribution, and be in the demand that the 10KV aerial condutor in the economic development supports, the insulator crossarm that the purpose of this utility model is a kind of not easy fracture of design, body is light, anti-soil power is strong.
The utility model has been realized above-mentioned purpose of design preferably, it is made of gold utensil 1, gold utensil 2, high strength insulation porcelain stamen rod and insulation full skirt, gold utensil 1 and gold utensil 2 the two in opposite directions direction respectively have the post hole, garden that an internal diameter equates, respectively have a semi-round groove on adjacent two faces of gold utensil 1 atresia, gold utensil 2 has a flat handle, have bolt hole on the handle, insert in the post hole, garden of two gold utensils at high strength insulation stamen rod two ends, post hole, garden internal diameter on its external diameter and the gold utensil adapts, the stamen rod is with the insulated umbrella skirt outward, full skirt is solid, and the centre is a cavity, plug and cavity tight fit.
Because this cross-arm adopts the synthetic non-metallic insulation materials to make, the variation of its structure and material uses this insulator crossarm to have that body is light, flexural strength is high, resistant to pollution advantage, can adapt to the electric distribution network trolley line support demand that constantly develops fully.
Describe the utility model in detail below in conjunction with accompanying drawing:

Fig. 2 gold utensil 1 sectional view
Fig. 3 gold utensil 1 vertical view
Fig. 4 gold utensil 2 sectional views
Fig. 5 gold utensil 2 vertical views
This insulator crossarm is made of gold utensil 1, gold utensil 2, high strength insulation porcelain rod 3, insulation full skirt 4.Gold gold utensil 1 respectively has post hole, a garden 5,6 on the direction in opposite directions with gold utensil 2, gold utensil 1 upwards, respectively have a semi-round groove on the face of both direction forward, gold utensil 2 has a flat handle 7, has bolt hole 8 on it.Insulation full skirt 4 is made by silicon rubber, and its center is a cavity, and full skirt partly is solid, and the cavity internal diameter is slightly less than several of stamen rod outside diameters.Before being inserted in, the heating full skirt makes its expansion earlier, is inserted in the stamen rod then, promptly tightly pounds on the stamen rod after the full skirt cooling.Post hole, garden internal diameter adapts in stamen rod outside diameter and the gold utensil, a small amount of sealing compound of full-filling before inserting, and after solidifying, stamen rod and gold utensil tight fit and sealing.
