【 系统概述 】System overview
耐火型母线槽由涂有防火涂料的外壳，包缠耐火陶瓷化复合带的母线和由耐火绝缘材料制成的支架组成。支架上开有多个长腰孔槽，由水平压板及垂直压板将耐火母线固定于支架上。在母线槽的一端有母线槽连接始端箱，在母线槽内有母线分接盒。耐火型母线槽具有优良的绝缘性能，既可在正常环境中连续使用，又可在失火环境中连续使用 1 小时到 3 小时以上，可适用于高层建筑及重要设施中，如安装有发电机的重要厂房及办公场所等，代替耐火电缆起输配电作用，其输电电流等级大，维修方便可靠，使用年限远比电缆长久，综合使用成本远低于耐火电缆。
There a fireproof coating covers on the busbar, wrap the ceramic composite tape and made by fireproof isolation materials.Some elliptical holes in the support part, the vertical and horizontal plates fix the fireproof busbar on the support parts. There is the connection beginning box at its one side, the tap box inside the busbar. It has a good isolation capability, can be used continuous both in normal and fire environment last 1 to 3 hours, which can used in high building and important establishment, such as the plant with generator or office place, what transmit powers instead of fireproof cables. Its current outgoing is high and easy of maintaining, use lifespan is longer than cable, and the complete cost is much lower than fireproof cable.
结构特点 structure feature
与一般的传统耐火母线相比，我公司的耐火母线槽具有以下明显优势：We have following advantages definitely than the traditional busbar:
1、采用合理的“三明治”相线紧密叠压结构设计，母线槽外形紧凑，体积小，母线系统具有阻抗低、电压降低、动热稳定性好的优点。
Closed and pressed Sandwiches ’design, compact appearance and small volume. There are some advantages like low impedance, decrease voltage and good dynamic thermal stability.
2、外壳采用冷成型薄钢型材混合组成。大电流等级的耐火母线我司采用，独创的双层壳体双层耐火涂料防护的优化结构，双保护结构可以有效阻止高温气体或明火直接进入母线槽内部。母线槽外壳表面为镀锌加喷防火涂料（遇火时，涂料能迅速以几何速度在母线表面膨胀，形成致密的碳化隔热层，密闭母线外壳所有缝隙，防止高温直接进入母线内部）。
The enclosure formed by cold shaped and thin steel. Out busbar with high current adopts an optimization structure with unique double housing and fireproof painting, the double protection can prevent the high temperature gas or fire from going inside the busbar. The housing surface covers the galvanization and fireproof painting. (the painting can expand in geometric speed immediately and form a dense carbonization insulation layer, close all the gaps and prevent the high temperature from going inside it.)
3、接头采用专用耐火型绝缘组件，连接可靠方便。
Special fireproof isolation parts of connection end, reliable and convenience connection.
4. 相排之间的绝缘采用母线国内外领先的陶瓷化复合带进行绝缘，其性能可靠，环保，无卤无毒，比由岩棉包覆的传统母线，散热好，温升低。生产方便。
The isolation between phase bars are advanced ceramic composite tape, reliable capability and environment protect. No halogen no poison. Better heating, lower temperature rise and more convenient production than traditional busbar.
