      -云南惠博桥架设备有限公司

母线干线系统是在日常用电行业中，一般是指低压供电中，负责传输供电，分散电能的一种重要的设备。
介绍电缆桥架厂的密集型耐火母线槽的特点、 应用场所； 将云南博电缆桥架厂的密集型耐火母线槽与传统电缆桥架厂生产的耐火电缆、 防火母线槽、 绝缘电缆进行对比；

 
云南惠博桥架厂设计师为你介绍母线槽发展史：
a. 第一代 电缆桥架、空气型母线槽 ： 上世纪 五十 年代中期起， 将导电排用绝缘衬垫支撑在壳体内， 靠空气介质绝缘。
b. 第二代  电缆桥架、密集型母线槽 ： 自上世纪 八十 年代中期开始， 将导电排用绝缘材料覆盖后再与两侧板紧固在一起。
c. 第三代  电缆桥架、复合绝缘型母线槽 ： 母线槽除了导电排本身具有绝缘层外， 各相间还有一定的空气介质绝缘， 并在各种弯头采用硫化绝缘技术新型电缆桥架及密集型耐火母线槽主要可应用于以下建 / 构筑物：

a. 城市商业综合体 、 大型教学大楼 、 高层医院建筑 、 疗养院、 高层酒店建筑、 高级公寓、 写字楼、 大型藏书馆；
b. 大型展馆和剧院建筑 、 金融大楼建筑 、 政府办公大楼建筑、 银行和保险大楼建筑、 广播电视大楼建筑、 电力调度和防灾指挥调度中心大楼建筑、 移动和电信大楼、 数据中心；
c. 城市轨道交通、 隧道、 人防工程；
d. 风电输电系统工程 、 太阳能输电系统工程 、 核电站应急电源输电系统工程。密集型耐火母线槽可应用于火焰条件下
， 在规定时间内需维持通电的下列场所或必须具备耐火性能的输配电设备：
Introduction of refractory busbar

Yunnan Bo Chao percussion Equipment Co., Ltd.

Busbar main line system is an important equipment in the daily electricity industry, which generally refers to low voltage power supply, which is responsible for transmission and distribution of power.

The characteristics and application places of the dense refractory busbar in the cable bridge plant are introduced, and the dense refractory busbar grooves of the Yunnan Bo cable bridge plant are compared with the fireproof cables, the fire proof busbar grooves and the insulated cables produced by the traditional cable bridge plant.

Yunnan Bo Chao bridge plant designer introduces you to the history of busbar development.

A. first generation cable bridge, air type busbar trough: in the mid 50s of the last century, the conductive insulation liner was supported in the shell and insulated by air medium.

B. second generation cable bridge, dense busbar slot: since the middle of the 80s of the last century, the electrical insulation materials are covered with insulating materials and then fastened with the two sides.

C. third generation cable bridge and composite insulated bus groove: the busbar slot has an insulating layer in addition to the insulating layer itself, and the insulating technology is used in various bends.

The new cable tray and dense fire-resistant busbar trough can be mainly applied to the following building / structures.

A. city commercial complex, large teaching building, high-rise hospital building, sanatorium, high-rise hotel building, Premium Apartment House, office building, large library;

B. large exhibition hall and theater building, financial building, government office building, bank and insurance building, broadcasting and television building building, power dispatching and disaster prevention and control center building, building, mobile and telecommunication building, data center;

C. urban rail transit, tunnel, civil air defense engineering;

D. wind power transmission system engineering, solar power transmission system engineering, nuclear power plant emergency power transmission system engineering. Dense fire-resistant busbar trough can be applied to flame condition.

In the prescribed time, the following places that need to maintain electricity must be equipped with fire resistant power transmission and distribution equipment.
