Feature introduction of cable tray

特色：机械强度高，它既有金属桥架的刚性又有玻璃钢桥架的韧性，耐腐蚀功能好、抗老化功能强、造型美观、装置方便、运用寿命长。环氧树脂及环氧树脂复合型电缆桥架适合在强腐蚀环境、大跨距、重载荷条件下运用。

Features: High mechanical strength, it has both rigidity of metal bridge and toughness of FRP bridge, good corrosion resistance, anti-aging function, beautiful appearance, convenient installation and long service life. Epoxy resin and epoxy resin composite cable bridge are suitable for use in strong corrosive environment, long span and heavy load conditions.

环氧树脂及环氧树脂复合型电缆桥架类型编制阐明：

Formulation of epoxy resin and epoxy composite cable tray type:

环氧树脂及环氧树脂复合型电缆桥架类型编制从结构上分：

The formulation of epoxy resin and epoxy composite cable bridge types is structured from:

1、槽式(C) 2、梯级式(T) 3、托盘式(P)

1, trough type (C) 2, cascade type (T) 3, pallet type (P)

环氧树脂及环氧树脂复合型电缆桥架标准的挑选：

Selection of epoxy resin and epoxy composite cable tray standards:

电缆填充率不超越规范规定值，动力电缆可取40-50%，控制电缆可取50-70%。另外，需预留10-25%的工程开展余量，桥架横截面积的挑选见下表。各种弯通及附件应契合工程布置条件，并与桥架配套。

The cable filling rate does not exceed the standard specified value, the power cable is 40-50%, and the control cable is 50-70%. In addition, it is necessary to reserve the allowance for the construction of 10-25%, and the selection of the cross sectional area of the bridge is shown in the table below. All kinds of bending and attachments should conform to the engineering layout conditions and match with the bridge frame.

电缆桥架除包括其自身的重量外，还应包括其所能接受的电线电缆的机械负载，作业均布载荷应不大于所挑选载荷等级额定均布载荷。电缆桥架在接受额定均布载荷时，其相对挠度环氧树脂及环氧树脂复合型的不宜大于1/200。

In addition to its own weight, the cable tray should also include the mechanical loads of the wires and cables it can accept, and the uniform load of the operation should not be greater than the rated uniform load of the selected load grade. When accepting rated uniform load, the relative deflection of cable bridge should not be greater than 1/200 of epoxy resin and epoxy resin composite type.

托盘式电缆桥架可备护罩，需求配护罩时可在订购时注明，其所有配件与梯级式，槽式桥架通用。

Pallet cable bridge can be equipped with protective shield. When required, it can be indicated when ordering. All its accessories are common with cascade and trough bridge.

槽式电缆桥架的护罩随槽体配套供货，其它配件与梯级式、托盘式桥架通用。用户如需槽式电缆桥架的其他品种标准可来图来函或面洽订购。

The shield of the trough cable bridge is supplied with the trough body. Other accessories are common with cascade and tray bridge. If users want standard of other types of trough cable bridge, they can send a letter or face to order.

大跨距电缆桥架备有盖板，需求配盖板时在订购时阐明，或按盖板类型订购。

Long-span cable bridges are equipped with cover plates, which are specified when ordering or ordered according to the type of cover plates.
