浅析蝶形引入光缆中金属加强件抽拔力影响因素

蝶形引入光缆外护多采用低烟无卤阻燃聚烯烃护套料,金属加强件一般采用镀铜钢丝和磷化钢丝。在生产过程中,加强件抽拔松将会影响蝶形引入光缆的整体性能,本文通过对比试验对挤塑温度、水槽温度、护套料类型、加强件类型等多方面分析论证加强件抽拔力松的原因。

Low smoke halogen-free flame retardant polyolefin sheathing materials are mostly used for the external protection of butterfly lead-in butterflycables, and copper plated steel wires and Phosphated steel wires are generally used for metal reinforcements. In the production process, thelooseness of the stiffener will affect the overall performance of the butterfly lead-in optical cable. This paper analyzes and demonstrates thereasons for the looseness of the stiffener from the aspects of extrusion temperature, water tank temperature, sheath material type, stiffener typeand so on.
