CN201854001U 中心竖直接地引下线的复合材料杆塔 失效 - 放弃

中心竖直接地引下线的复合材料杆塔
摘要：
本实用新型涉及一种中心竖直接地引下线的复合材料杆塔。该杆塔中地线横担采用金属材料，在地线横担的中心引出接地引下线，接地引下线从复合材料杆塔的正中心竖直引下接入大地，如果塔身下部分是钢管，接地引下线可直接联接在钢管上来接地。该实用新型利用了复合材料杆塔塔壁的绝缘强度，增强了线路耐雷电冲击的绝缘强度，避免了接地引下线短接复合材料杆塔塔身，发挥了复合材料塔身的绝缘作用，由于接地引下线从杆塔里侧穿入，避免了接地引下线暴露在外面受大风等外力的破坏，结构简单，易于实现。
摘要（英）：

The utility model relates to a composite tower with a vertical grounding down wire in the center. The ground wire cross arm on the top part of the tower adopts metal materials, the grounding down wire is led from the center of the ground wire cross arm and is vertically led down to be grounded from the center of the composite tower, and if the lower part of a tower body is steel tubes, the grounding down wire can be directly connected onto the steel tubes to be grounded. Since the insulating strength of the composite tower wall is utilized by the utility model, the insulating strength of lightning impulse resistance of the wire is enhanced, the phenomenon that the grounding down wire is in short circuit with the composite tower body is avoided, and the insulating effect of the composite tower body is realized; and since the grounding down wire is penetrated from the inner side of the tower, the problem that the grounding down wire is damaged by external forces such as strong wind because of being exposed outside is avoided, the structure is simple and the realization is easy.
