Abstract

The invention discloses an optical cable sheath metal strip, a preparation method and application thereof. The optical cable sheath metal strip includes a metal base strip and water-blocking grease lines arranged on the metal base strip. There are at least two water-blocking grease lines, which are interlaced to form several water-blocking chambers. During preparation, the water-blocking grease is continuously coated on the metal base belt by line spraying to form at least two continuous and interlaced water-blocking grease lines. In the present invention, the water-blocking ointment is coated on the metal strip in the form of lines, while simplifying the coating process, the amount of the water-blocking ointment can be greatly reduced, and the production cost is reduced. And the line-shaped water-blocking ointment is coated with multiple lines. These water-blocking ointment lines are interlaced to form a continuous water-blocking chamber arranged in a specific law. After the optical cable is coated, the formed water-blocking stripes are also in a specific Regular uniform and continuous distribution, excellent water-blocking effect, that is, the present invention can produce good water-blocking effect while reducing the amount of water-blocking ointment.

Description

Technical field [0001] The present invention belongs to the technical field of cable manufacture, and particularly relates to a sheathed metal strip cable preparation method and application. Background technique [0002] Optical fiber cable (optical fiber cable) in order to satisfy optical, mechanical or environmental performance specification is manufactured, it is the use of a sheath disposed clad optical fiber or fibers as the transmission medium and may be used individually or as a group of communication cable assembly. Most of the domestic production of fiber optic cable have adopted is based on the structure of metal with longitudinally outer sheath of the cable where the seepage is an important indicator of whether a qualified inspection of finished cable. Currently the main factor fiber optic cable jacket for water seepage metal lap failed to effectively fill the right amount of cream and cable seepage. [0003] To solve this problem, the prior art has taken a variety of ...
