电缆支架性能特点是什么?

  电缆支架性能特点显而易见不然也不会那么受欢迎,电缆支架的基本性能:

  Cable stand performance characteristics are obvious, otherwise it will not be so popular, the basic performance of cable support:

  1. 强度高,可设计性好:连续纤维增强热固性复合材料主要由起增强作用的玻璃纤维和起粘结作用,传递载荷作用的热固性树脂组成。玻璃纤维的拉伸强度很高(3450mpa),其含量,长度,铺设形式决定支架制品的强度。 热固性的玻璃纤维增强复合材料强度可以在30-1000mpa范围。因此,我们根据产品的受力情况,产量,生产工艺,价格承受能力来设计玻璃纤维的用量,长度和铺设形式。

  1., high strength, good design: continuous fiber reinforced thermosetting composite material, mainly by strengthening the role of glass fiber and adhesive role, the role of the transfer of thermosetting resin composition. The tensile strength of glass fiber is very high (3450mpa), and its content, length and laying form determine the strength of the bracket. Thermosetting glass fiber reinforced composites can be strength in the 30-1000mpa range. Therefore, according to the force, yield, production process and price bearing capacity of the product, we design the dosage, length and laying form of the glass fiber.

  2.不蠕变:连续纤维增强热固性复合材料支架的刚性比美国某公司生产的纤维增强增强尼龙支架增加一倍。即使在长期负载下也不变形,也不会出现像某些城市地铁使用的金属制电缆支架那样往下倾斜。

  2. non creep: the stiffness of the continuous fiber reinforced thermosetting composite scaffold is doubled compared with the fiber reinforced nylon support produced by a company in the United states. Even under long-term load, it will not deform, and there will be no downward inclination of the metal cable bracket used in the subway in some cities in china.

  3.防火:氧指数是评价电缆放火产品重要的检测手段。 氧指数是指在大氧气条件下,防火产品耐烧的特性。在工程中使用应根据燃烧强度确定。例如,在30根电缆的条件下,如发生电缆引燃事故,在4min以内即可形成500度以上高温热聚集,从而导致电缆沿走向进行延燃。电缆密集处的电缆越多,可燃体质量越大。在30根电缆时,单位长度可燃体质量为20.5kg/m,现在以300根电缆计算,单位长度可燃体质量为158kg/m,按大可能产生燃烧强度计算,氧指数要不小于65%。我们认为,产品防火标准中氧指数定在70%比较合适。

  3. fire prevention: oxygen index is an important means to evaluate the cable ignition products. Oxygen index refers to the maximum oxygen conditions, fire products burning resistance characteristics. In engineering, the use shall be based on the strength of the combustion. For example, under the condition of 30 cables, if a cable ignition accident occurs, a high temperature heat accumulation of more than 500 degrees can be formed within 4min, thus causing the cable to be ignited along the direction. The greater the cable density, the greater the mass of the combustible material. In 30 cables, fuel per unit length of body mass as 20.5kg/m, now calculated by 300 cables, fuel per unit length of body mass of 158kg/m, calculated according to the maximum possible intensity of combustion, the oxygen index or less than 65%. We believe that the product fire standard, oxygen index set at 70% is more appropriate.

  根据使用要求我们研制的复合材料电缆支架的氧指数大于等于70%。符合防火低烟,无卤,无毒的安全要求。防火性能以高于台湾“地下铁路用玻璃纤维塑胶电缆槽板技术规范(氧指数为52%),也比美国某公司的增强热塑性支架高的多。本指标已不低于经英国BS认证的香港地铁启用新车辆使用的复合材料防火标准的指标。

  According to the requirement, the oxygen index of composite cable scaffold developed is larger than or equal to 70%. Comply with fire, smoke, halogen free, non-toxic safety requirements. The fire performance is higher than the technical specification for Taiwan Metro glass fibre plastic cable trough (oxygen index 52%), which is much higher than that of an American company's reinforced thermoplastic stent. This target is no less than the target of composite fireproofing standards for new vehicles used by the British BS certified Hongkong metro.

  4.耐腐蚀:连续纤维增强热固性复合材料支架耐腐蚀,尤其适合在潮湿,盐雾,酸和弱碱环境使用。

  4. corrosion resistance: continuous fiber reinforced thermosetting composite material stand against corrosion, especially suitable for use in humid, salt, fog, acid and weak base environment.

  5.电缘性:缘性能可以根据使用要求调整。1) 电缘型,缘电阻大于1000GΩ;2) 抗静电型,表面电阻小于10GΩ。

  5. electrical insulation: insulation performance can be adjusted according to use requirements. 1) electrical insulation type, insulation resistance greater than 1000G; 2) antistatic, surface resistance is less than 10G.
