济南电缆桥架装置弹簧圈的好处

  济南电缆桥架主要由玻璃纤维增强材料和无机黏合剂复合的防火板与金属骨架复合以及其他的防火基材而组成.

  Ji'nan cable bridge is mainly composed of glass fiber reinforced material and inorganic adhesive composite fireproof board and metal skeleton compound and other fireproof base material

  外层加入防火涂料,从而使得防火电缆桥架遇火后不会燃烧,对火势蔓延起一定阻隔作用,具有极其良好的防火阻燃效果,同时还具有具有耐火、耐油、耐腐蚀、无毒、无污染,整体安装方便,结构合理,使用寿命长,并且美观,电缆安装在电缆桥架中,环境整洁,清扫方便.防火涂料有涂层薄、耐火极限高、粘接力强的特点.

  The outer join fire retardant coating, so that the fireproof cable tray without burning fire, the fire spread a barrier, with a fire retardant effect is extremely good, but also has the fire resistance, oil resistance, corrosion resistance, non-toxic, no pollution, convenient installation, reasonable overall structure, long service life, and appearance, cable installed on the cable tray, the environment clean and tidy, convenient cleaning. Fire retardant coating has the characteristics of thin coating, high fire resistance and strong cohesion.

  电缆桥架的接地问题:

  Earthing problem of cable bridge:

  1、沿桥架全长另敷设接地干线时,每段(包括非直线段)桥架应至少有一点与接地干线可靠连接.

  1, along the length of the bridge to lay the ground line, each paragraph (including non linear section) bridge should be at least a little reliable connection with the grounding trunk

  2、桥架系统应具有可靠的电气连接并接地(只对金属桥架).

  2 the bridge system shall have reliable electrical connections and earthing (only for metal bridge)

  3、对于振动场所,在接地部位的连接处应装置弹簧圈.

  3. For the vibration site, the spring shall be installed at the joint of the grounding part

  4、当允许利用桥架系统构成接地干线回路时应符合下列要求.桥架端部之间连接电阻应不大于0.00033欧姆,接地孔应清除绝缘涂层.在1KV及以下中性点直接接地系统中,受电设备的接地与系统中性线接地相连.装有处动切断供电装轩时,桥架的级长方向金属横截面积应不小于规定值.

  4, when allowed using the bridge system composed of grounding line circuits should meet the following requirements. The bridge between end connection resistance should be less than 0.00033 ohm, grounding hole should remove the insulation coating at 1KV and below the neutral grounded system, electrical equipment grounding system with neutral grounding connected. A dynamic assembly when the power supply is cut off, the prefect direction of metal cross section bridge should be not less than the specified value.
