适用范围 Scope of application

NHJX 系列耐火型母线槽适用于交流三相四线、三相五线 制，频率50～60Hz, 额定电压至660V, 额定工作电流 250～6300A的供配电系统。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 连续使用一小时以上，可适用于高层建筑及重要设施中，

代替耐火电缆起输配电作用。

NHJX Series Refractory busbarslots are suitable for AC three- phase   four-wire   and   three-phase   five-wire   systems   with frequencies of 50-60 Hz,rated voltage of 660 V and rated working current of 250-6300A.Fire-resistant busbar groove has excellent insulation performance.It can be used continuously in normal environment and in fire environment for more than one hour.It can be used in high-rise buildings and important facilities instead of fire-resistant cables to play the role of transmission and distribution.

产品特点 Product characteristics

1.耐火型母线槽除在电气性能上有绝缘母线槽之优点外， 更具有独特的防火性能。其导电材料选用高导电率的铜或

铝导体材料，绝缘采用云母及高强陶瓷材料，母线外壳

2.母线槽外壳采用优质高强度冷轧钢或铝镁合金型材制 作，并采用双层隔热且内外采用防火材料处理。耐火型母 线槽外壳开有通风孔，发生火灾时，防火涂料能迅速膨

胀，隔断热源。

3.耐火型母线槽绝缘材料为高温云母带，耐高温950℃;   4.耐火型母线槽由涂有防火涂料的外壳，包缠耐火云母带 的母线和由耐火绝缘材料制成的支架组成。支架上开有多 个凹槽，凹槽内置入母线并将其固定。在母线槽的一端有

母线槽连接盒，在母线槽内有母线分接盒。

1.Fire-resistant busbar groove has the advantages of insulated busbar groove in electrical performance and unique fire-proof performance.Its conductive materials are copper or aluminium conductors   with   high   conductivity,mica and   high   strength ceramics for insulation and busbar housing.

2.Bus channel shell is made of high-quality and high-strength cold-rolled   steel   or   Al-Mg   alloy   profiles,with   double-layer heat insulation and fireproof material inside and outside.Fire- resistant busbar groove shell is provided with ventilation holes. When a fire occurs,the fire-proof coating can expand rapidly and cut off heat source.

3.The insulating material of refractory busbar groove is high temperature mica tape with high temperature resistance of 950 C.

4.The fire-resistant busbar groove consists of a shell coated with fire-resistant paint,a busbar wrapped with fire-resistant mica tape   and   a   bracket   made   of   fire-resistant   insulating material.A plurality of grooves are arranged on the bracket, and buses are inserted into the grooves and fixed.At one end of the busbarslot,there is a busbarslot connection box,and in the busbarslot,there is a busbar tapping box.

主要技术参数 Main technical parameters

1.频率50～60Hz, 额定电压至660V, 额定工作电流
