橋架連接一般不用使用內連接片，通常應用外連接片較多，自然倘若你要想橋架更牢固，你里外一起裝也是可以的，不外我感覺沒必要，實際意義并不大，人力成本也高了。 橋架連接應滿足下述標準：

Generally, the internal connecting piece is not used for bridge connection, and the external connecting piece is often used. Naturally, if you want to make the bridge more firm, you can install it inside and outside. However, I don't think it's necessary, the practical significance is not great, and the labor cost is also high. The bridge connection shall meet the following standards:

1.平行線段鋼質電纜線橋架長短超出30m，鋁合金型材或玻鋼質橋架長短超出15m時，配有伸縮器；電纜線橋架超越建筑變形縫處設定賠償設備。

1. when the length of steel cable tray in parallel section exceeds 30m, and the length of aluminum alloy profile or glass steel tray exceeds 15m, it shall be equipped with an extender; Compensation equipment shall be set at the place where the cable tray exceeds the building deformation joint.

2.電纜線橋架應在以下地區設定支架或支架：

2. the cable tray shall be provided with supports or supports in the following areas:

橋架連接頭兩邊0.5m處；

0.5m on both sides of bridge connector;

每間隔1.5～3m處；

At an interval of 1.5 ~ 3M;

拐彎處；

Turning point;

豎直橋架每過1.5Km。

Every 1.5km of vertical bridge.

3. 支架和支架安裝維持豎直、干凈整潔、堅固、無傾斜狀況。

3. support and support installation shall be vertical, clean, tidy, firm and free of inclination.

4. 橋架連接板螺絲固定不動牢固無遺漏，螺帽坐落于橋架兩側。

4. the screws of the bridge connecting plate shall be fixed firmly without omission, and the nuts shall be located on both sides of the bridge.

5. 纜橋架應埋設在易燃易爆物品氣體管道和供熱管道的下邊。

5. the cable tray shall be buried under the flammable and explosive gas pipeline and heat supply pipeline.

6. 金屬材料橋架以及支架總長應不少于2處接地裝置或接零。

6. the total length of metal material bridge and support shall not be less than 2 grounding devices or neutral connections.

7. 金屬材料橋架間連接片兩邊不少于2個有緊固螺絲帽或防松螺母的連接固定不動地腳螺栓，而且連接片兩邊跨接線不小于4mm2的銅芯電線接頭。

7. there shall be no less than 2 fixed foundation bolts with fastening screw caps or locknuts on both sides of the connecting piece between metal material bridges, and the jumper wire on both sides of the connecting piece shall be no less than 4mm2 copper core wire joints.

濟南電纜橋架廠家經過調查發現，甚多人們在安裝連接時螺釘是外朝里安裝的，這個是不正確的作法，因為在裝線的情況下，會把電纜表皮刮傷，那樣會得不償失，這一點要注意。

After investigation, Jinan cable tray manufacturers found that many people install the screws from the outside to the inside when installing the connection, which is incorrect, because the cable skin will be scratched when installing the line, which will not pay off the gains. This should be noted.
