FIELD: optical modules with anti-corrosion cover. ^ SUBSTANCE: method for manufacturing an optical module with anti-corrosion aluminum cover, which is sprayed onto the surface of free buffer tube made of stainless steel includes following stages: spraying of fine aluminum powder onto the surface of free buffer tube made of stainless steel by melting the aluminum template with electric arc heating and spraying of melted aluminum with compressed air. Also, heating of aluminum cover layer up to temperature between 100 and 700°C, rolling of heated layer of aluminum cover to reduce porosity and deviations in thickness of aluminum cover layer and fast cooling of rolled layer of aluminum cover to prevent worsening of working properties of elements inside the optical module. Before the spraying stage, included additionally is the stage of preliminary heating of free buffer tube made of stainless steel up to temperature between 50 and 100°C. before the preliminary heating stage, included additionally is the stage of jet machining of the surface of the free buffer tube of stainless steel to create convex and concave sections. Optical cable, inbuilt in lightning protection cable, includes one or more optical modules, manufactured in accordance to the method. ^ EFFECT: increased productivity, reduced cost of products, reduced porosity and thickness deviations of resulting aluminum cover layer, which prevents corrosion of aluminum cover layer. ^ 2 cl, 4 dwg |
