Abstract
The utility model discloses a plastic insulating sleeve tube, which is composed of a conductive rod, a thermal insulating protective layer and a plastic insulating tower body, wherein, the plastic insulating tower body is formed via plastic injection molding and provided with a sleeve tube flange and a plastic umbrella skirt, the plastic tower body is fixed to the conductive rod via nuts, and the thermal insulating protective layer is arranged between the tower body and the conductive rod. The plastic insulating sleeve tube having simple structure and favorable mechanical property can be made into transformer sleeve tubes, capacitor sleeve tubes, etc. The plastic insulating sleeve tube having high temperature resistance is not easy to seep oil and crack.
Description
The utility model relates to a kind of insulating sleeve as lead-out wires such as transformer, power capacitors.
Be applied in transformer, porcelain bushing on the switch cubicle, and with rubber cushion sealing, by casting die the porcelain tower is fixed on the fuel tank between fuel tank and the conducting rod, this oil sealing structure with the passing of time can oxidation because of rubber cushion, because of variations in temperature, rubber cushion follows the string, and particularly goes up rubber cushion, because conducting rod working temperature and fault temperature make rubber cushion aging, cause the equipment oil impregnate, and increase maintenance capacity.
The purpose of this utility model is to provide a kind of plastic insulation sleeve pipe, have high temperature resistant, oil-tight, the characteristics of good mechanical property.
The utility model plastic insulation sleeve pipe is made up of conducting rod, heat insulation sheath, plastic insulation tower body, and the plastic insulation tower body is fixed on the conducting rod by nut, and heat insulation sheath is set between plastic insulation tower body and the conducting rod.The plastic insulation tower body is formed by plastic injection-moulded, and the plastic insulation tower body is provided with casing flange and plastics full skirt; Heat insulation sheath with asbestos or glass fibre and mixed with resin after, be squeezed on the conducting rod.This plastic insulation sleeve pipe and fuel tank can directly be used the bolt crimping, do not need rubber cushion.
The utility model plastic insulation sleeve pipe, simple in structure, good mechanical property, conducting rod are provided with heat insulation sheath, make the plastic insulation sleeve pipe high temperature resistant, are difficult for breaking, and the injection molded good seal of plastic insulation sleeve pipe is difficult for oil impregnate.
Fig. 1 is the front view of the utility model plastic insulation sleeve pipe;
The plastic insulation sleeve pipe is made up of conducting rod 1, heat insulation sheath 3 and plastic insulation tower body 4 as shown in the figure, the plastic insulation tower body is fixed on the conducting rod by pad 6 and nut 7, heat insulation sheath 3 is set between tower body 4 and the conducting rod 1, the plastic insulation tower body is formed by plastic injection-moulded, and tower body is provided with casing flange 5 and plastics full skirt 2.
