电缆桥架厂家技能在不断的革新,企业也加强了对电缆桥架质量的管理,从而进一步完善了它的生产工艺,为行业开展带来了有利的条件,也给电缆施工和电缆装置带来了便利与好处。
The skills of cable tray manufacturers are constantly innovating, and enterprises have also strengthened their management of cable tray quality, further improving their production processes, bringing favorable conditions for industry development, and also bringing convenience and benefits to cable construction and cable installation.
电缆桥架的分类:梯级式线缆桥架、托盘式线缆桥架梯级式线缆桥架Q1-T型梯级式电缆桥架是依据国内外有关资料而改进设计的。它具有重量轻、成本低、造型别具、装置便利、散热、透气好等长处。他适用于一般直径较大电缆的敷设,适合于高、低压动力电缆的敷设。托盘式线缆桥架托盘式电缆桥架是石油、化工、轻工、电讯等方面使用广泛的一种。它具有重量轻、载荷大、造型漂亮、结构简单、装置便利等长处。它即适用于动力电缆的装置,也适合于操控电缆的敷设。
The classification of cable trays: stepped cable trays, tray type cable trays. The Q1-T type stepped cable trays have been improved and designed based on relevant domestic and foreign data. It has advantages such as light weight, low cost, unique design, convenient installation, good heat dissipation, and breathability. It is suitable for laying cables with larger diameters and for laying high and low voltage power cables. Tray type cable tray tray is a widely used type in petroleum, chemical, light industry, telecommunications, and other fields. It has advantages such as light weight, large load, beautiful design, simple structure, and convenient installation. It is suitable for both the installation of power cables and the laying of control cables.

桥架的装置:横平竖直,弯头处要陡峭。当桥架分层时,好用组合架。桥架内部要加设防火封堵或加设防火包。钢制30米,铝合金及塑料的15米要加伸缩节。过建筑物变形缝处(伸缩缝、沉降缝)加补偿装置。桥架的支架间距一般要求水平的为1.5-3米,垂直的为2米一个。螺母坐落桥架的外侧。当支架与铝合金桥架连接时,留意防电化办法。留意转弯处支架的设置。配电室大型桥架要采用可调式组合支架 大型工程桥架弯曲度要共同。
The installation of the bridge should be horizontal and vertical, with steep bends. When the bridge is layered, it is easy to use a combination frame. Fire blocking or fire protection packages should be installed inside the bridge. Steel 30 meters, aluminum alloy and plastic 15 meters require expansion joints. Install compensation devices at the deformation joints (expansion joints, settlement joints) of the building. The spacing between the supports of the bridge is generally required to be 1.5 to 3 meters horizontally and 2 meters vertically. The nut is located on the outer side of the bridge. When connecting the bracket to the aluminum alloy bridge, pay attention to anti electrochemical methods. Pay attention to the setting of brackets at turns. The large cable tray in the power distribution room should use adjustable combination supports, and the bending degree of the large engineering cable tray should be common.
槽式桥架
Trough type cable tray
电缆桥架在有防火要求的区段内,可在电缆梯架、托盘内增加具有耐火或难燃功能的板、网等资料构成封闭或半封闭式结构,并采纳在桥架及其支吊架外表涂刷防火涂层等办法,其整体耐火功能应满足有关规范或规范的要求。在工程防火要求较高的场所,不宜采用铝合金电缆桥架。
In sections with fire protection requirements, cable trays can be equipped with fire-resistant or flame-retardant boards, nets, and other materials to form a closed or semi closed structure. Measures such as applying fire-resistant coatings on the surface of the cable tray and its supports and hangers should be adopted, and its overall fire resistance function should meet the requirements of relevant national regulations or specifications. Aluminum alloy cable trays should not be used in places with high fire protection requirements in engineering.
槽式电缆桥架宽度和高度的挑选应符合填充率的要求,电缆的梯架和托盘内的填充率在一般情况下,电力电缆可取40~50,操控电缆可取50~70,且宜预留10~25工程开展裕量。在挑选电缆桥架的荷载等级时,电缆桥架的工作均布荷载不应大于所选电缆桥架荷载等级的额外均布荷载,如果电缆桥架的支吊架的实际跨距不等于2m 时,则工作均布荷载应满足要求。
The selection of the width and height of the trough type cable tray should meet the requirements of filling rate. In general, the filling rate in the cable ladder and tray can be 40-50 for power cables and 50-70 for control cables, and a margin of 10-25 should be reserved for engineering development. When selecting the load level of the cable tray, the working uniform load of the cable tray should not exceed the additional uniform load of the selected cable tray load level. If the actual span of the support and hanger of the cable tray is not equal to 2 meters, the working uniform load should meet the requirements.
