Abstract:
The present invention relates to an underbracing for an arch-shaped utility pole used to firmly erect a utility pole. The underbracing for an arch-shaped utility pole of the present invention is molded with just conductive concrete and general concrete since the conductive concrete layer disposed at the lower part of the underbracing for an arch-shaped utility pole is mixed with metal fragments during molding. The conductive concrete layer is connected to the reinforcing steel in the utility pole underbracing, and an additional lead wire is connected to the reinforcing steel. Therefore, the automation facility for an existing underbracing for an arch-shaped utility pole may be applied without changes so that the utility pole underbracing of the present invention can be suitable for mass production, and the error rate of the utility pole underbracing of the present invention may be close to zero so that the utility pole underbracing can be highly economical. The metal fragments in the conductive concrete layer further increase the grounding efficiency fn the conductive concrete layer by having the effect of reducing high grounding resistance, and the grounding efficiency can increase while production costs can be reduced even without using an expensive ground plate because the lead wire is welded directly with the thick reinforcing steel.

본 발명은 전주를 세워 설치하는 건주 공사시에 전주의 견고한 근착을 위해 사용되는 아치형 전주근가에 있어, 그 아치형 전주근가의 하부에 위치하는 도전성 콘크리트층에 금속조각을 혼합하여 성형하고, 상기 도전성 콘크리트층은 전주근가 내부의 보강철근과 접속되게 하며, 별도의 리드선은 상기 보강철근과 연결되도록 구성함으로써, 도전성 콘크리트와 일반 콘크리트만으로 성형이 이루어지므로 기존 아치형 전주근가의 자동화 설비를 그대로 적용시킬 수 있어 대량 생산에 매우 적합함은 물론 불량이 거의 발생하지 않아 매우 경제적인 것이고, 도전성 콘크리트층 내부의 금속조각은 도전성 콘크리트층에 대한 접지 효율을 가일층 향상시켜 접지 저항의 저감 효과가 매우 뛰어난 것이며, 굵은 보강철근에 리드선을 직접 용접함에 따라 고가의 접지판을 사용하지 않고도 접지 효율은 향상되고 생산 원가는 크게 절감되는 것이다.
Abstract:
The present invention relates to a telegraph pole for an underground cable, including a pole body, a transformer, and a transformer case. The pole body stands upright with a lower end thereof buried under the ground, and is internally equipped with a service wire connected to a main wire buried under the ground, an electric circuit, a high-tension line for receiving high voltages from the service wire, and a low-tension line for supplying low voltages to an electricity consumer cable buried under the ground. The transformer is installed on the top of the pole body, transforms high voltages input from the high-tension line into low voltages and outputs the low voltages to the low-tension line. The transformer case is arranged outside the transformer to protect the transformer. The telegraph pole for an underground cable of the present invention has advantages of minimizing the space occupied by a transformer and a switch during construction of the underground cable, ensuring safety of people from high voltage wires, and achieving advertising effects and aesthetic enhancement in a city landscape by attaching advertising materials or installing lighting fixtures on the transformer case.

Abstract:
The circular rim, which has the dielectric properties is attached to the insulator in a manner so that the wire which is under voltage is held approximately in the centre of the circular rim. The highest point of the circular rim bears a small plate with spikes preventing the birds from landing on what is in fact the highest point of the circular rim. The circular rim will also prevent the birds from getting into the dangerously close vicinity from the high voltage wire through stepping on the console supporting the insulators.
