江苏春晨电缆有限公司生产扁电缆YGCB3*80+2*14+4*15,硅橡胶扁电缆产品概述:
硅橡胶扁电缆采用硅橡胶作绝缘或护套材料,由于硅橡胶本身具有耐高温、耐寒、柔软、耐磨、防腐等特性,因此该电缆高温环境下电气性能稳定,抗老化性能好,使用寿命长,适合于交流1KV及以下具有抗拉、耐热、防腐等特殊要求的行车、台车、传输机械等移动设备和电器用动力传输线及控制、照明、通讯线路,本产品已广泛应用于冶金、电力、化工、船舶、港口等行业。美国首先进行实验研究并实现了“等电位”作业的方法,等电位作业的方法才在美国全国范围内推广。目前,美国已经在765KV及以下各个电压等级的线路上广泛开展带电作业,并进行了1000KV特高压人体接触带电体的实验。
The United States first carried out experimental research and realized the method of "e" operation, and the method of e operation was popularized nationwide in the United States. At present, the United States has carried out a wide range of live work on 765kV and below lines, and carried out experiments on 1000kV EHV human contact with live bodies.
日本的带电作业
Live working in Japan
日本开展带电作业是20世纪40年代初期,日本引进美国带电作业技术的方式,通过消化吸收,逐渐形成自己的特点。扁电缆YGCB3*80+2*14+4*15初期日本的带电作业工具和作业项目几乎全部照搬美国。1962年,日本开始在220KV输电线路上开展带电作业,1972年,已经在500KV超高压输电线路上自由进行带电作业。日本在配电线路开展的带电作业最具特色,他们开发的配电带电作业工具种类繁多、规格齐全,尤其是防护用具和屏蔽用具,适用于各个配电电压等级。
In the early 1940s, Japan introduced live working technology from the United States, and gradually formed its own characteristics through digestion and absorption. In the early days, the live working tools and projects in Japan were almost copied from those in the United States. In 1962, Japan began to carry out live work on 220kV transmission lines, and in 1972, it has carried out live work on 500kV EHV transmission lines freely. Japan's live working on distribution lines is the most characteristic. The tools they developed for live working on distribution lines are various and complete in specifications, especially protective and shielding devices, which are applicable to all distribution voltage levels.
日本的带电水冲装置和水冲洗方法在世界上居于先进水平。日本的大多数变电站都安装有固定水冲洗装置,甚至于500KV变电站都装有固定水冲洗装置,而清扫输电线路绝缘子串的清洗工具有40余种,仅清扫500KV长串耐张绝缘子串的自动清洗机就有多种。
Japan's charged water flushing device and water flushing method are at the advanced level in the world. Most substations in Japan are e with fixed water flushing devices, even 500kV substations are e with fixed water flushing devices, and there are more than 40 cleaning tools for cleaning insulator strings of transmission lines, and there are many kinds of automatic cleaning machines only for cleaning 500kV long tension insulator strings.
