产品详情资料
 0ºC和高风压600 N/m²下运行。
c、 测量交叉导线和架空导线之间的垂直间隙时
导体在80ºC无风条件下工作。
d、 高压电路应始终与低压电路交叉。尽可能地
交叉口应垂直于既有线并靠近结构。
e、 任何配电或服务架空导线不得跨越建筑物屋顶,
游泳池、运动场和炼油厂。
f、 来自无线电和电视天线、水箱、标志、烟囱和其他装置
(不属于建筑物),配电线路的小水平间隙应
为3米。
g、 参考低压服务降四芯电缆的正常离地间隙,
街道上的离地间隙可能减少到4米。
h、 男子不应在相邻线路下穿越。
i、 中压线路与所有其他结构(包括树木)的小间隙应为2m。
10.10极耙
导线张力(横向荷载)作用的电杆,例如角度或
终端杆应耙平。耙的方向应确保导线张力
部队试图拉直柱子。倾斜与垂直方向的角度应约为3º。
10.11长直线
在长直线上,每10极应为一节极。这加强了这条线
并可方便后期线路维护。
10.12危险标志和号码牌
所有13.8 kV和33 kV电杆必须在线路安装前安装高压危险标志
 ng at 80 ºC and highest wind pressure 600 N/m².
c. Vertical clearances between crossing and overhead conductors measured when
conductors are operating at 80 ºC with no wind.
d. High voltage circuits shall always cross over lower voltage circuits. As far as possible
the crossing should be perpendicular to the existing line and near to the structure.
e. Any distribution or service overhead conductors shall not cross over the roof of building,
swimming pools, sports area and oil refinery under any circumstances.
f. From radio and television antennas, water tanks, signs, chimney and other installations
(not classified as buildings), the minimum horizontal clearance of distribution lines shall
be 3 m.

g. With reference to the normal ground clearance for LV service drop Quadruplex cable,
the ground clearance may be reduced to 4m over streets.
h. Guys should not cross under an adjacent line.
i. Minimum clearance for MV lines from all other structures including trees shall be 2 m.
10.10 Pole Rake
Poles on which conductor tension forces (permanent transverse load) act, such as angle or
terminal poles, should be raked. The direction of rake is such that the conductor tension
forces try to straighten the pole. The angle of rake from vertical should be approximately 3º.
10.11 Long Straight Line
On long straight lines, every 10th pole should be a section pole. This strengthens the line
and can facilitate maintenance of the line at a later stage.
10.12 Danger Sign And Number Plate
