Abstract

The utility model relates to a fiberglass ledge, which comprises a ledge body, wherein the ledge body is made of fiberglass compound material, which is from the outside to the inside a glass fiber alkali-free continuous felt, a glass fiber compound felt, a glass fiber compound felt and a long glass fiber layer. The utility model has the advantage of being light in weight, good in intensity, impact resistance, dielectrically property, corrosion resistance and heat resistance.

Description

The glass fiber reinforced plastic cross-arm

Technical field

The utility model belongs to the used accessory of a kind of distribution network, particularly a kind of glass fiber reinforced plastic cross-arm.

Background technology

Distribution network in the city tens thousand of the electric poles of high-low pressure that distributing, electric pole is provided with cross-arm and golden part.The main wooden cross arm of existing cross-arm and two kinds of iron cross arms.The wooden cross arm poor fire, intensity is low, the life-span is short.The problem that iron cross arm exists is: 1, anti-corrosive properties are poor.Handle though galvanizing is carried out on the iron cross arm surface, after in a few years using, just can not using of corrosion must be changed, thereby cause very big material and artificial consumption.And, in construction, often because the corrosion of cross-arm is not got off the porcelain vase dismounting.When changing porcelain vase, to so, promptly incur loss through delay the time of maintenance and processing accident, increase electric quantity loss again with cross-arm under the iron sawing.2, poor insulativity.Be in operation,, then cause major accident in case the insulation of porcelain vase is destroyed.3, energy loss is big.Though the anti-flammability of iron load is better, the iron that is in operation load easily produces eddy current, causes energy loss.In addition, existing cross-arm end face is the plane, easily causes rainwater in the accumulating of cross-arm surface, and influences the insulating properties of cross-arm.

Summary of the invention

The purpose of this utility model is to solve the problem that prior art exists, provide a kind of in light weight, specific strength good, dielectric properties are good, corrosion resistance and the good glass fiber reinforced plastic cross-arm of heat resistance.

Technical solution of the present utility model is: it has a cross-arm body, said cross-arm body is made by glass fiber reinforced plastics composite material, and is followed successively by glass fiber alkali-free continuous felt, glass fiber composite mat, glass fiber composite mat, long glass fibres layer by top layer to nexine.

According to above-mentioned glass fiber reinforced plastic cross-arm, said cross-arm body end face is the arcwall face of middle part projection, influences insulating properties to prevent surface area water.

The utility model has the advantages that: in light weight, specific strength good, shock resistance, corrosion resistance and heat resistance is good, dielectric properties are good, because the cross-arm end face is an arcwall face, can prevent that rainwater from the accumulating of cross-arm surface, therefore not influencing the insulating properties of cross-arm.

The specific embodiment

As shown in the figure, the utility model has a strip cross-arm body 1, said cross-arm body 1 is made by glass fiber reinforced plastics composite material, and be followed successively by glass fiber alkali-free continuous felt 11, glass fiber composite mat 12, glass fiber composite mat 13, long glass fibres layer 14 by top layer to nexine, be provided with installing hole 2 in the side of cross-arm body 1, the end face 3 of cross-arm body 1 is the arcwall face of middle part projection.

Claims

1, a kind of glass fiber reinforced plastic cross-arm comprises the cross-arm body, it is characterized in that: said cross-arm body is made by glass fiber reinforced plastics composite material, and is followed successively by glass fiber alkali-free continuous felt, glass fiber composite mat, glass fiber composite mat, long glass fibres layer by top layer to nexine.

2, glass fiber reinforced plastic cross-arm according to claim 1 is characterized in that: said cross-arm body end face is the arcwall face of middle part projection.
