Environmental impact of the life cycle of overhead cables

It is reported that the current business environment is becoming increasingly complex and ever-increasing pressure on the environment background, overhead cable during the entire life cycle environmental impacts in the end how to become a focus of attention. Life cycle assessment is an evaluation of a product, process, or activity, from raw material acquisition to production, transportation, sales, use, reuse, maintenance, and final disposal of the entire life cycle stage of the process of environmental impact.

Overhead cable product life cycle environmental impacts of the main contribution coming from the use phase of the cable, the environmental impact of more than 98% of the contribution rate, age was calculated using the stage for 30 years, a relatively huge loss of electricity generated, using the cable scenarios have a direct relationship, the use of different scenarios and different useful lives will affect the calculation results in a great extent. Secondly, access to raw materials from the product stage, accounting for about 1 percent, is the smallest contribution to the transport stage of the product, accounting for less than a million. Thus, to reduce the power loss during transmission is to reduce the environmental impact of the life cycle of the overhead cable by the most important and most effective and important means feasible.

For overhead cable manufacturers, it is proposed to start the conductor itself and improve the production process starting, and further improve the purity metals and alloys technology, increasing its conductivity, and narrowing the gap with the developed countries to reduce reactive power consumption. You can also choose from raw materials, reduce energy consumption, reduce transport distances and product recycling and other aspects of overhead cable and minimize environmental impact.
