Embodiment Construction
[0009] As shown in the figure, the outdoor insulating support terminal 1 of the present invention is made of outdoor epoxy resin, modified acid anhydride as a fixing agent, silicon micropowder as a filler, polyether as a toughening agent, and benzyldimethylamine as an accelerator. Color paste, according to the ratio of epoxy resin 100: fixing agent 100: filler 370: toughening agent 2: accelerator 0.15: color paste 1.2, after APG process, there are metal inserts 2 and terminals for fixing screws at both ends body together by die-casting and solidification, the length of the supporting terminal is small, only 320-350mm, and the supporting terminal skirt 3 is an umbrella-shaped sheet structure with a slope of 13-16°.

Abstract
The present invention relates to a outdoors insulation support terminal for fixing 35 cable. It contains outdoors epoxy, modifying acid anhydride used as fixing agent, silicon micro powder used as padding, polyether used as plasticizer, benzyl dimethylamine used as added colour paste, through APG technology and according to certain of proportion, compression casting solidifying two ends metal embedded piece with terminal body. Said Support terminal is low gradient umbrella shape sheet structure with small length dimension and more umbrella skirts, having advantages of compactness, low cost, high mechanical strength, fine electrical performance, and strong anti ultraviolet ray ability.
Description
technical field [0001] The invention relates to an outdoor insulation support terminal for fixing 35KV cables. Background technique [0002] High-voltage cables are heavy and have high voltage levels. The overhead support members not only require high tensile strength, bending resistance, and cannot be broken, but the most important thing is to have strong electrical insulation properties. The commonly used outdoor high-voltage cable supports in China use traditional ceramic electric porcelain. Because the porcelain skirt of ceramic electric porcelain is constrained by mechanical strength, the slope of the porcelain skirt cannot be too large, and the creepage distance of a single piece of porcelain skirt is limited. Usually, the length of the cable support is increased to increase the creepage distance to meet the insulation of the line. need. The disadvantage of ceramic electric porcelain is that it is large in size, poor in mechanical strength, easy ...
