在电力传输的 “生命线” 上，电缆与桥架的摩擦如同一场无声的战争。当电缆外皮被反复磨损，短路风险便如影随形，轻则引发电路故障，重则威胁设备。而桥架内衬陶瓷涂层的出现，恰似为电缆披上一层坚不可摧的 “铠甲”，以创新工艺化解磨损与短路的双重危机。

　　On the lifeline of power transmission, the friction between cables and cable trays is like a silent war. When the outer layer of the cable is repeatedly worn, the risk of short circuit follows closely, ranging from minor circuit failures to serious threats to equipment safety. The emergence of ceramic coating on the inner lining of cable trays is like putting an indestructible "armor" on cables, resolving the dual crisis of wear and short circuit with innovative technology.

　　电缆磨损导致短路的根源，在于传统桥架与电缆长期接触产生的机械摩擦。在工业环境中，电缆随设备震动、热胀冷缩不断位移，桥架内壁的金属材质或粗糙表面，如同砂纸般持续刮擦电缆外皮。一旦外皮破损，内部导体暴露，短路事故便一触即发。尤其是在高频震动、高负载运行的场景下，普通桥架的耐磨性能捉襟见肘，频繁更换电缆不仅成本高昂，还严重影响电力系统的稳定性。

　　The root cause of short circuits caused by cable wear is the mechanical friction generated by long-term contact between traditional cable trays and cables. In industrial environments, cables constantly move with equipment vibration, thermal expansion and contraction, and the metal material or rough surface of the inner wall of the cable tray continuously scratches the cable sheath like sandpaper. Once the outer layer is damaged and the internal conductor is exposed, a short circuit accident is imminent. Especially in scenarios of high-frequency vibration and high load operation, the wear resistance of ordinary cable trays is limited. Frequent replacement of cables not only incurs high costs, but also seriously affects the stability of the power system.

　　陶瓷涂层之所以能成为 “破局者”，源于其独特的材料特性。陶瓷本身硬度极高，仅次于金刚石，将其以涂层形式附着在桥架内壁，相当于给电缆铺设了一条光滑的 “陶瓷轨道”。当电缆与涂层表面接触时，极低的摩擦系数大幅降低磨损力度，即便在持续震动或大幅度位移中，电缆外皮也能得到有效保护。此外，陶瓷涂层还具备优异的耐高温、耐腐蚀性能，即使在高温、潮湿或腐蚀性气体环境中，也不会因自身老化而失去防护作用，为电缆提供长期稳定的保护屏障。

　　The reason why ceramic coatings can become "disruptors" is due to their unique material properties. Ceramics themselves have extremely high hardness, second only to diamond. Attaching them in the form of coatings to the inner walls of cable trays is equivalent to laying a smooth "ceramic track" for cables. When the cable comes into contact with the coating surface, the extremely low friction coefficient significantly reduces the wear force, and even in continuous vibration or large displacement, the cable sheath can be effectively protected. In addition, ceramic coatings also have excellent high temperature resistance and corrosion resistance. Even in high temperature, humid, or corrosive gas environments, they will not lose their protective effect due to aging, providing a long-term stable protective barrier for cables.

　　桥架内衬陶瓷涂层的应用并非简单的材料叠加，而是一套精密的工艺体系。，需要对桥架内壁进行预处理，通过喷砂、打磨等方式去除表面油污、锈迹和杂质，确保涂层与基体的附着力。随后，采用热喷涂、静电喷涂等技术将陶瓷粉末均匀附着在桥架内壁。热喷涂工艺利用高温火焰将陶瓷粉末熔化后喷射到基体表面，形成致密的涂层；静电喷涂则通过静电吸附原理，使陶瓷粉末均匀包裹桥架内壁，两种方法各有优势，但都需严格控制喷涂厚度与均匀度。喷涂完成后，还需经过高温烧结或固化处理，使陶瓷涂层与桥架基体紧密结合，形成坚固的防护层。

　　The application of ceramic coating for bridge lining is not a simple material stacking, but a precise process system. Firstly, it is necessary to pre treat the inner wall of the bridge frame by removing surface oil stains, rust, and impurities through sandblasting, grinding, and other methods to ensure the adhesion between the coating and the substrate. Subsequently, ceramic powder was uniformly adhered to the inner wall of the bridge using techniques such as thermal spraying and electrostatic spraying. The thermal spraying process uses high-temperature flames to melt ceramic powder and spray it onto the surface of the substrate, forming a dense coating; Electrostatic spraying uses the principle of electrostatic adsorption to evenly wrap ceramic powder around the inner wall of the bridge. Both methods have their own advantages, but both require strict control of the spraying thickness and uniformity. After spraying, it is necessary to undergo high-temperature sintering or curing treatment to tightly bond the ceramic coating with the bridge substrate, forming a strong protective layer.

　　实际应用中，陶瓷涂层桥架展现出显著的防护效果。在震动频繁的生产车间，安装陶瓷涂层桥架后，电缆磨损速度降低了 80% 以上，原本每半年就需更换的电缆，使用寿命延长 3 - 5 年。在沿海潮湿环境或化工区域，陶瓷涂层的耐腐蚀特性有效阻止了盐分、化学气体对电缆的侵蚀，避免因外皮脆化导致的短路隐患。此外，陶瓷涂层表面光滑易清洁，减少了灰尘、杂物的堆积，进一步降低了因异物摩擦引发的电缆损伤风险。

　　In practical applications, ceramic coated cable trays exhibit significant protective effects. After installing ceramic coated cable trays in a production workshop with frequent vibrations, the wear rate of cables has been reduced by more than 80%. Cables that originally needed to be replaced every six months have been extended in service life to 3-5 years. In humid coastal environments or chemical areas, the corrosion resistance of ceramic coatings effectively prevents the erosion of cables by salt and chemical gases, avoiding the risk of short circuits caused by brittle outer skin. In addition, the ceramic coating surface is smooth and easy to clean, reducing the accumulation of dust and debris, further reducing the risk of cable damage caused by foreign object friction.

　　从磨损威胁到守护，桥架内衬陶瓷涂层不仅是材料的革新，更是电力防护理念的升级。这层薄薄的 “陶瓷铠甲”，以硬核性能为电缆保驾护航，大幅降低短路事故发生率，为电力系统的稳定运行筑牢防线。在追求与的现代工业领域，陶瓷涂层桥架正以可靠的表现，书写着电缆防护的新篇章。

　　From the threat of wear and tear to safety protection, the ceramic coating on the bridge lining is not only an innovation in materials, but also an upgrade in the concept of power protection. This thin layer of "ceramic armor" provides strong protection for cables with its hardcore performance, significantly reducing the incidence of short circuit accidents and building a solid defense line for the stable operation of the power system. In the modern industrial field that pursues efficiency and safety, ceramic coated cable trays are writing a new chapter in cable protection with reliable performance.
