Problems solved by technology

The main reason is that this kind of high-performance PE fiber material is easy to destroy its high-quality performance after being subjected to high temperature, and the production process requires high
However, the optical cables produced by traditional technology using aramid fibers are significantly lower in terms of tensile strength, sunlight aging resistance, corrosion resistance, etc., and the weight of the product is heavier, making it more difficult to lay large-scale construction.

Abstract

The invention discloses a manufacturing method of PE fiber and a rod for a layer-stranding cable, and is characterized in that a PE fiber rod replaces FRP (Fiber Reinforced Plastic) as a central reinforcing piece, aramid fiber is replaced by the PE fiber, and an outer jacket part subjected to heat processing is separated through a process of coating a layer of a polyimide film or a polyimide insulation tape, so that the temperature cannot be higher than the maximum temperature limit of a PE fiber yarn in a manufacturing process. According to the method, advantages of an ultra-high molecular PE fiber yarn and the rod are utilized to reinforce using performance of the cable and avoid damage to the performance of the ultra-high molecular PE fiber yarn and the rod in a high-temperature production process.

Description

technical field [0001] The invention relates to the technical field of communication optical cables, in particular to a PE fiber layer stranded optical cable and a manufacturing method thereof. Background technique [0002] Ultra-high-strength PE fiber is also called ultra-high molecular weight polyethylene (UHMWPE) fiber, also known as high-strength high-modulus polyethylene fiber. It is a high-performance fiber successfully developed in the early 1980s. , High-strength and high-modulus polyethylene fiber), it is a fiber with a highly oriented extended chain structure. [0003] Ultra-high-strength PE fiber has high axial specific tensile strength and stiffness, extremely high specific modulus, outstanding impact resistance and cutting resistance toughness, good chemical stability such as low temperature resistance, abrasion resistance and ultraviolet resistance, etc. It also plays a pivotal role in safety protection, aerospace, aviation, aerospace and other fields. It has...
