Cable tray is the general name of continuous rigid structural system supporting cables, which is composed of tray, straight ladder, elbow, accessories, supports and hangers, etc. Jinan cable bridge is a cable laying equipment that makes the laying of wires, cables, pipelines and cables standardized, serialized and universal.

高分子電纜橋架在機械工業中的應用越來越廣泛。“以塑代鋼”、“以塑代鐵”已成為材料科學研究的熱點。這種研究拓寬了材料的選擇范圍，使機械產品從傳統的笨重、高消耗轉向輕便、耐用、經濟。如聚氨酯彈性體，聚氨酯彈性體的耐磨性尤為突出。聚合物主要用于電氣和電子工業中的絕緣、屏蔽、導電和磁性材料。

Polymer cable tray is more and more widely used in mechanical industry. "Replacing steel with plastic" and "replacing iron with plastic" have become the focus of material science research. This research broadens the selection range of materials and makes the mechanical products turn from the traditional bulky and high consumption to light, durable and economical. Such as polyurethane elastomer, the wear resistance of polyurethane elastomer is particularly prominent. Polymers are mainly used as insulation, shielding, conductive and magnetic materials in the electrical and electronic industries.

高分子電纜橋架分為槽式、托盤式和梯式，由支架、支臂和安裝附件組成。全橋可獨立架設，也可附著于各種建(構)筑物及管廊支架上，體現了結構簡單、外形美觀、配置靈活、維護方便的特點。所有部件需要鍍鋅并安裝在建筑物外的開放式橋架上，如果靠近海洋或在腐蝕區域，則材料需要具有防腐、防潮、良好附著力和高沖擊強度的物理特性。

Polymer cable tray is divided into trough type, tray type and ladder type, which is composed of support, support arm and installation accessories. The whole bridge can be erected independently or attached to various buildings (structures) and pipe gallery supports, reflecting the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All components need to be galvanized and installed on the open bridge outside the building. If it is close to the sea or in the corrosive area, the material needs to have the physical characteristics of anti-corrosion, moisture-proof, good adhesion and high impact strength.

高分子電纜橋架是一種耐腐蝕、使用壽命長、能耗低、綠色環保、功能齊全的新型電纜橋架產品。

Polymer cable tray is a new type of cable tray product with corrosion resistance, long service life, low energy consumption, green environmental protection and complete functions.

綜上所述，高分子電纜橋架是濟南電纜橋架的一種，它具有電纜橋架所不具有的一些優勢，而且是一種新型的環保產品，在工業行業應用普遍。

To sum up, polymer cable bridge is a kind of cable bridge in Shandong. It has some advantages that Jinan cable bridge does not have, and it is a new type of environmental protection product, which is widely used in the industrial industry.
