应用于世博变电站的大型电缆放线装置方案

Payout device schemes for large size cables for Shibo Substation

500 kV世博变电站进线工程选用的大型电缆,其导体截面为2 500 mm2,部分电缆盘毛重约为35 000kg。为确保电缆盘安全快速的施放,综合分析后选用了大型放线装置配套方案,现场应用表明了该方案的可行性,可为同类工程施工提供借鉴。

The large size cable used for 500 kV Shibo Substation has the conductor cross section of 2 500 mm2 and some reels are as heavy as 35 000 kg.To ensure safe and quick payout of such large cable reels,a payout device scheme was proposed and was proved feasible by field application.
