Introduction
This document from ELEKTROTECHNISCHE WERKE FRITZ DRIESCHER & SÖHNE GMBH discusses bird protection measures for overhead power lines and outdoor switches. It highlights the risks posed to large birds by certain power line designs and outlines solutions to mitigate these risks.

Specifications and Standards
The document references Section 8.10 of the DIN VDE Regulation 0210, which mandates that components of overhead power lines should be designed to prevent birds from perching near live conductors. This is crucial to avoid faults and losses caused by birds coming into contact with conductors.

Bird Protection Solutions
The bird protection means are made from fibrous glass reinforced polyester and are designed for easy handling and quick assembly. They are applicable for both overhead power lines and outdoor switches. The document provides examples of mounting these protection means on various structures, including concrete columns, wooden poles, and terminal towers.

Retrofitting Procedures
Retrofitting existing columns with bird protection means is described as straightforward and can be performed by power line operators. The protection means are delivered disassembled, facilitating transport and assembly. Fastening is achieved through screwing or clamping, with additional options available upon request.

Illustrations and Examples
The document includes several figures illustrating different mounting configurations and examples of bird protection means on various structures. These visual aids support the text by providing practical examples of implementation.

Conclusion
The bird protection means offered by DRIESCHER are designed to protect both wildlife and electrical infrastructure. They are adaptable to various structures and easy to install, making them an effective solution for reducing bird-related hazards in power line systems.
