高阻燃玻璃布包带
High flame-retardant performance glass fabric tapes
● 产品介绍 Introduction
适合作各种阻燃和耐火电缆的绕包带和隔火阻燃层。对于交联聚乙烯绝缘电缆，当选用本系列高阻燃、隔氧、隔火包带作为成缆包带，并选用本公司的矿物纸绳作为填充，将有可能实现电缆的阻燃或提高电费的阻燃等级。
This product is suitable for a variety of flame-retardant and fire-resistant cable as the wrapping tape and fire retardant layer. For cross linked polyethylene insulating cable, the application of this series with high flame-retardant oxygen insulation and fire insulation performance as the cable tape, as well as our mineral paper yarn as the filler, will make it possible to achieve a flame or improve flammability rating.

● 隔火层在阻燃电缆中的作用
Role of the flame-proof tape in the flame retardant cable
1、用于包扎电缆中的绝缘线芯。使绝缘线芯的结构保持稳定。
2、确保缆芯不松散和绝缘不被划伤。
3、隔离绝缘层和外护层以及内衬层，以防它们之间相互粘结而影响电缆的机械、物理、电性能等。
4、当电缆遭到燃烧时，能够吸收大量的热量，并形成碳化层，隔绝气层、保护绝缘层免受燃烧，使火灾的损失不致于进一步扩大化。
1. To dress the cable insulated core, so that the structure of insulated core will be stable.
2. To prevent the cable core from being loose, and the insulation from being scratched.
3. To separate the insulation, sheath and inner covering, and keep them from bonding and affecting the mechanical, physical and electrical properties of the cable.
4. When the cable was burning, a lot of heat can be absorbed, and form a carbon layer to isolate the gas and protect the insulation layer from burning, so that the loss will be cut.
