Feature introduction of cable tray

特色：機械強度高，它既有金屬橋架的剛性又有玻璃鋼橋架的韌性，耐腐蝕功能好、抗老化功能強、造型美觀、裝置方便、運用壽命長。環(huán)氧樹脂及環(huán)氧樹脂復合型電纜橋架適合在強腐蝕環(huán)境、大跨距、重載荷條件下運用。

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.

環(huán)氧樹脂及環(huán)氧樹脂復合型電纜橋架類型編制闡明：

Formulation of epoxy resin and epoxy composite cable tray type:

環(huán)氧樹脂及環(huán)氧樹脂復合型電纜橋架類型編制從結構上分：

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

1、槽式(C) 2、梯級式(T) 3、托盤式(P)

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

環(huán)氧樹脂及環(huán)氧樹脂復合型電纜橋架標準的挑選：

Selection of epoxy resin and epoxy composite cable tray standards:

電纜填充率不超越規(guī)范規(guī)定值，動力電纜可取40-50%，控制電纜可取50-70%。另外，需預留10-25%的工程開展余量，橋架橫截面積的挑選見下表。各種彎通及附件應契合工程布置條件，并與橋架配套。

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.

電纜橋架除包括其自身的重量外，還應包括其所能接受的電線電纜的機械負載，作業(yè)均布載荷應不大于所挑選載荷等級額定均布載荷。電纜橋架在接受額定均布載荷時，其相對撓度環(huán)氧樹脂及環(huán)氧樹脂復合型的不宜大于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.

托盤式電纜橋架可備護罩，需求配護罩時可在訂購時注明，其所有配件與梯級式，槽式橋架通用。

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.

槽式電纜橋架的護罩隨槽體配套供貨，其它配件與梯級式、托盤式橋架通用。用戶如需槽式電纜橋架的其他品種標準可來圖來函或面洽訂購。

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.

大跨距電纜橋架備有蓋板，需求配蓋板時在訂購時闡明，或按蓋板類型訂購。

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