你知道电缆支架的技术指标吗?

2017/06/16  浏览次数:

  电缆支架是用于支撑电缆的设备,在很多工程中都有使用,电缆支架厂为生产出支架产品,更应遵守支架主要技术指标。

  Cable support is used to support cable equipment, in many projects are used, cable support factory for the production of high quality stent products, but also should comply with the main technical indicators of support.

  电缆支架的技术指标主要包括尺寸要求、承载力、氧指数、弯曲强度、拉伸强度、耐电弧和缘电阻等。在尺寸方面,支撑梁长度>300mm时,支撑面宽度应>50mm,支撑梁高度应>50mm;支撑梁长度<300mm时,支撑面宽度应>40mm,支撑梁高度应>40mm;对于直埋式电缆支架来说,外露支撑梁长度>300mm,墙内固定长度应大于240mm;支撑梁长度在250-300mm之间时,墙内固定长度应>180mm;支撑梁长度小于250mm,时,墙内固定长度应大于120mm。电缆桥架厂生产的直埋式支架承载力应>250KG,螺栓式支架应>200KG。氧指数>60%,弯曲强度为140,拉伸强度为60,耐电弧为180,缘电阻为1.01013。按照以上主要技术标准,才能生产出基本符合要求的电缆支架产品。

  The technical indexes of the cable support include the size requirements, carrying capacity, oxygen index, bending strength, tensile strength, arc resistance and insulation resistance. In size, the support beam length >300mm, width >50mm should support, the support beam height should be >50mm; the support beam length <300mm, width >40mm should support, the support beam height should be >40mm; for the buried cable bracket, exposed support beam length >300mm, wall fixed length should be greater than 240mm; the length of the support beam in 250-300mm, the wall fixed length should be >180mm; Liang Changdu is less than 250mm, when the wall fixed length should be greater than 120mm. The bearing capacity of the directly buried support produced by the cable bridge factory shall be >250KG, and the bolt support shall be >200KG. The oxygen index >60%, flexural strength is 140, tensile strength is 60, arc resistance is 180, and insulation resistance is 1.01013. In accordance with the above major technical standards, in order to produce basically meet the requirements of the cable stent products.
