14次级架空线路
14.1概述
二次配电线路从低压侧分配能量
变压器二次架空配电电压通常为220/127伏
住宅和商业区，工业区为380/220伏。
服务下降电缆是系统的一部分，用于从
从属于消费者的场所。。
14.2导线和跨距
标准二次导线为120平方毫米四芯导线，额定电流为290安培。
图14.1显示了二次线长度与KVA之间的关系
电压降为4%。基本跨度为50m。
服务下降电缆为四芯50平方毫米。
14.3电杆/拉线
所有极位置的标准低压电网极为10米长的OC10。
基础深度为1.5米。
对于16º至60º的中等角度电杆，需要一根拉线。角度超过60º至90º
需要两次停留。有关停留的详细信息，请参阅10.0节。
14.4施工
四联杆的中性点连接在杆顶部下方50 mm处，如所示
正常低压OC10电杆的施工图130至138和
自支撑OC10SFS杆。
14.5架空服务的连接
四联交联聚乙烯绝缘铝。3x50mm²，带ACSR/AW 1x50mm2裸中性线
用于额定电流为125安培的架空服务跌落电缆。图纸139&
140显示了架空服务连接的详细信息。压缩型PG
带有绝缘盖的铝制连接器用于二次网络连接。(c) Crossarms shall be placed on the side of the pole facing the curve, angle, corner, steep
grade and terminal pole.
14 SECONDARY OVERHEAD LINES
14.1 General
The secondary distribution lines distribute energy from the low voltage side of the
transformer. The secondary overhead distribution voltage is normally 220/127 volts for
residential and commercial area, and 380/220 volts for industrial area.
Service drop cable is the portion of the system which makes the final connection from the
secondary to the consumer’s premises..
14.2 Conductor And Span Length
The standard secondary conductor is Quadruplex 120 sq.mm with a rating of 290 Amps.
Drawing 14.1 shows the relationship between the length of secondary line and KVA to give
a voltage drop of 4 %. Basic span length is 50 m.
Service drop cable is Quadruplex 50 sq. mm.
14.3 Poles / Stays

The standard low voltage network pole is OC10 of 10 meter length for all pole positions.
Foundation depth is 1.5 meter.
One stay is required for medium angle poles for angles 16º to 60º. Angles over 60º to 90º
require two stays. Refer to sec.10.0 for the details of stays.
14.4 Construction
The neutral of Quadruplex is bonded 50 mm below the top of the pole as shown in
construction drawings 130 to 138 for normal LV OC10 poles and drawings 141 to 145 for
self support OC10SFS poles.
14.5 Connection To Overhead Service

Quadruplex XLPE insulated Aluminium.3x50mm² with ACSR/AW 1x50mm2 bare neutral
is used for overhead service drop cable having current rating 125 Amp. Drawings 139 &
140 are showing the details of overhead service connection. Compression type PG
aluminum connectors with insulated covers are used for the secondary network connections.
