摘要
依据电缆制备所用耐火材料种类,介绍云母绕包带耐火电缆、矿物绝缘耐火电缆、陶瓷化硅橡胶耐火电缆的特点。简要介绍国内中压耐火电缆的研究现状,并结合具体工程案例介绍10 kV超A类阻燃隔离型中压耐火电缆在隧道工程中的应用。
This paper introduces the characteristics of fire resistant-cables with mica wrapping tape, mineral insulated fire-resistant cables and ceramic silicone rubber fire-resistant cables according to the types of refractory materials used in cable preparation. It briefly introduces the research status of domestic medium-voltage fire-resistant cables, and introduces the applicability of 10 kV class A ＋ flame-retardant isolated medium-voltage fireresistant cables in tunnel engineering application in combination with specific project cases.
