大圈径光纤保护管是我公司独自研发生产的，乃全国首家。该产品采用的是316进口不锈钢材料，大大的加强了管子的抗压，抗拉性能，更加完整的保护了光纤内光纤维丝线的易断。相比较于同类产品在弯曲时造成内部电线易折断的问题，该产品对此有了革命性的改良，提高弯曲性能，加大弯曲半径，其最小折弯半径为85mm，从而更好的保护了内部的线路和塑性管路。

Big Circle Diameter Optical Fiber Protective Metal Hose is our company's own R & D production as the country's first. The product is imported 316 stainless steel material, greatly enhanced compressive, tensile performance of the hose, complete protection of the optical fiber cable fiber yarns easily broken. Compared to similar hose causing internal wire breakage problem when bent, the product which has a revolutionary improvement, improved bending performance, increase the bending radius,the minimum bend radius of 85mm, better protection of the interior of the line and plastic pipe road.
