玻璃钢在电力绝缘方面的应用 The application of glass reinforced plastic in electrical insulation 公共设施领域里最危险的安全隐患之一就是电线杆顶端起火，引起火灾。这种火灾风险的增加或减少取决于电线杆的结构和设计所选用的材料。一些公共事业服务公司已将玻璃钢横杆使用于他们的电力传输和基础设施之中，以减小风险。 One of the most dangerous safety hazards in the public sector is the fire at the top of the pole. The increase or decrease of this fire risk depends on the structure and the materials selected for the design. Some utilities have already used glass-reinforced steel rods in their power transmission and infrastructure to reduce risk. 横杆是电线杆顶端用于电力传输和分配的最重要的组件之一。以往传统的建造材料都是木材，现在已经有用钢铁和和玻璃钢作材料制作的横杆了。 The horizontal bar is one of the most important components of power transmission and distribution at the top of the pole. Traditionally, the traditional building materials were made of wood, which is now made of steel and fiberglass. 玻璃钢电力横担是以玻璃纤维为基材，浸以环氧树脂经过模具热固引拔成型的一种新型电力器材，被广泛地用于架空绝缘线路上做各种开关、避雷器等固定用横担。 Power cross arm is based on the material of glass fiber, glass fiber reinforced plastic dip in after mold thermosetting epoxy resin drawing forming of a new type of power equipment, is widely used in making all kinds of switches, overhead insulated line lightning arrester and fixed with cross arm. 1、其表面采用聚酯表面毡，从而提高产品的抗老化性； The surface adopts polyester surface felt to improve the anti-aging properties of products. 2、管内有聚氨酯发泡剂，以增加横担的强度和防止雨水渗透； There is a polyurethane foaming agent in the tube to increase the strength of the cross and prevent the water from penetrating. 3、且矩形管两端有塑料盖。 3, the rectangular tube has plastic cover on both ends. 玻璃钢电力横担具有重量轻.比强度好.抗冲击.介电性能优良.耐腐蚀性合耐热性能好等优点，解决了现有木横担和铁横担的防腐性能差，阻燃性能差，强度底，绝缘性差，能源损失大，使用寿命短等缺点。 Glass fiber reinforced plastic power cross arm has a light weight. Is better than strength. Impact resistance. Excellent dielectric properties. The advantages of good corrosion resistance and heat resistance performance, solves the existing wooden cross arm and the anti-corrosion performance of iron cross arm is poor, flame retardant performance is poor, strength, poor insulation, energy loss is large, short life and other shortcomings.
