Galvanized cable tray has become a common cable tray in the market because of its wide application range and low cost. However, many people will question whether there is a need for jumper wires for Shandong galvanized bridge? The answer is needed.

山東電纜橋架

Shandong cable tray

鍍鋅橋架的材料為“電鍍鋅”，即化學(xué)清洗后將鋼板放入電鍍液(含氧化鋅)中。通電后，鋅分子電離并附著在鋼板表面，形成鍍鋅橋。

The material of galvanized bridge is "electro galvanized", that is, after chemical cleaning, put the steel plate into electroplating solution (including zinc oxide). After energization, zinc molecules ionize and adhere to the surface of the steel plate to form a galvanized bridge.

跨接線原理：

Jumper principle:

跨接導(dǎo)線是連接到電氣設(shè)備外殼上的線路，用于及時(shí)輸出各種原因引起的不電荷或泄漏電流。由于鍍鋅電纜橋架由金屬制成，具有一定的導(dǎo)電性，為了防止電流因泄漏或其他原因在鍍鋅電纜橋架動(dòng)，通常在電纜橋架上跨接。

Jumper wire is a line connected to the enclosure of electrical equipment, which is used to output unsafe charge or leakage current caused by various reasons in time. Since the galvanized cable tray is made of metal and has certain conductivity, in order to prevent current from flowing on the galvanized cable tray due to leakage or other reasons, it is usually bridged on the cable tray.

跨接線注意事項(xiàng)：

Jumper precautions:

1.金屬電纜橋架及其支架全長應(yīng)少與接地(PE)或中性(pen)干線連接2處;

1. The total length of metal cable tray and its support shall be connected with grounding (PE) or neutral (pen) trunk line at least 2 places;

2.非鍍鋅電纜橋架之間的連接板兩端應(yīng)采用銅芯地線連接，地線的小允許截面積不小于4平方毫米;

2. Both ends of the connecting plate between non galvanized cable trays shall be connected with copper core ground wire, and the minimum allowable cross-sectional area of the ground wire shall not be less than 4mm2;

3.鍍鋅電纜橋架之間連接板的兩端不得與接地線交叉，但連接板的兩端不得少于2個(gè)連接固定螺栓，并帶有防松螺母或防松墊圈。

3. The two ends of the connecting plate between galvanized cable trays shall not cross the grounding wire, but the two ends of the connecting plate shall not be less than 2 connecting and fixing bolts, and shall be equipped with anti loose nuts or anti loose washers.

以上就是關(guān)于山東鍍鋅橋架需不需要做跨接線的回答，答案是肯定的。原因就是為了防止電流泄露或者倒流，總之是為了起見。希望本文章能夠?qū)δ兴鶐椭缒€想了解更多關(guān)于橋架的知識(shí)，請持續(xù)關(guān)注我們網(wǎng)站!

The above is the answer about whether there is a need for jumper wire for Shandong galvanized bridge. The answer is yes. The reason is to prevent current leakage or backflow.
