Light cable plate strip for power system and preparation method of light cable plate strip

Abstract

The invention discloses a light cable plate strip for a power system and a preparation method of the light cable plate strip. The light cable plate strip comprises a protective shell layer, a core material and plastic pipelines; the core material is made of foaming cement with the compressive strength not lower than 5 MPa and the volume weight not higher than 800 kg / m<3>, and the plastic pipelines are evenly distributed in the core material and used for cables to penetrate through; and the protective shell layer wraps the core material and is used for protecting the core material and the plastic pipelines in the protective shell layer, and the protective shell layer is made of reactive powder concrete. The prepared cable plate strip has better waterproof, anti-seepage and anti-erosion performance, compared with a common concrete cable plate strip, the self weight is reduced by nearly 40%, the material consumption is greatly reduced, the production cost is reduced, site construction is facilitated, and the site construction effect is improved.

Description

technical field

[0001] The invention relates to a cable strip, in particular to a light cable strip used in a power system and a preparation method thereof. Background technique

[0002] Prefabricated buildings have become an important way for the transformation and upgrading of the construction industry due to their energy saving and environmental protection, high productivity, stable product quality, and the deep integration of the construction industry and informatization industrialization. Adopting the concept of prefabricated buildings in the distribution network civil engineering is of great significance for improving the construction quality and progress of power grid projects, reducing costs and increasing efficiency, and comprehensively carrying out the standardized construction and transformation of distribution networks. It has broad prospects in power engineering. market expectation.

[0003] The existing cable slabs are integrally prefabricated by ordinary conc...
