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.

高分子电缆桥架在机械工业中的应用越来越广泛。“以塑代钢”、“以塑代铁”已成为材料科学研究的热点。这种研究拓宽了材料的选择范围，使机械产品从传统的笨重、高消耗转向轻便、耐用、经济。如聚氨酯弹性体，聚氨酯弹性体的耐磨性尤为突出。聚合物主要用于电气和电子工业中的绝缘、屏蔽、导电和磁性材料。

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.

高分子电缆桥架分为槽式、托盘式和梯式，由支架、支臂和安装附件组成。全桥可独立架设，也可附着于各种建(构)筑物及管廊支架上，体现了结构简单、外形美观、配置灵活、维护方便的特点。所有部件需要镀锌并安装在建筑物外的开放式桥架上，如果靠近海洋或在腐蚀区域，则材料需要具有防腐、防潮、良好附着力和高冲击强度的物理特性。

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.

高分子电缆桥架是一种耐腐蚀、使用寿命长、能耗低、绿色环保、功能齐全的新型电缆桥架产品。

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.

综上所述，高分子电缆桥架是 济南电缆桥架的一种，它具有电缆桥架所不具有的一些优势，而且是一种新型的环保产品，在工业行业应用普遍。

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.
