Wildlife and Asset Protection Solutions for Overhead Lines

Introduction to Asset Protection

Asset protection is fundamental to ensuring the reliability and efficiency of the national grid, especially at critical points like substations. Substations serve as the backbone of electrical energy transmission and distribution, acting as points that connect the grid to homes, businesses, and essential services. However, these sites are frequently exposed to risks from wildlife, such as birds and other animals, which can cause faults, equipment damage, and unexpected power outages. Substations are connected to various power sources and the grid, facilitating the integration and reliable transmission of electricity. For contractors seeking solutions, implementing advanced protection measures—like insulating and isolating components—can significantly reduce these risks. By proactively safeguarding substations and associated equipment, utilities can prevent electrical faults, minimize costly disruptions, and maintain the safe, continuous flow of power. Effective asset protection not only shields vital infrastructure from wildlife but also supports contractors and utilities in delivering reliable electrical energy to communities.

Understanding Substations

Substations are pivotal facilities within the electrical grid, responsible for transforming electrical energy between different voltages to ensure safe and efficient delivery to end users. There are two primary types: transmission substations and distribution substations. The main difference between these is that a transmission substation operates at high voltages for long-distance transmission across the grid, while a distribution substation operates at lower voltages, stepping down power to levels suitable for local distribution to homes and businesses. Each substation is equipped with specialized electrical equipment, such as transformers, switches, and circuit breakers, with the transformer playing a key role in converting voltage levels for efficient transmission and distribution. Understanding the function and structure of substations helps contractors and utilities recognize the importance of protecting these assets from wildlife and other hazards. By implementing robust protection solutions, the risk of faults and equipment damage caused by animals can be significantly reduced, ensuring the safe and reliable operation of both transmission and distribution networks.

Ensuring Network Reliability and Preventing Outages

Possums, birds, rats, snakes, and squirrels are all capable of causing power outages. These animals often climb on substations, and birds frequently perch on transformers as they seek safe, warm places to shelter and nest. Even small birds or rodents can create problems by attracting larger predators.

When wildlife interacts with electrical equipment, it can result in various issues such as electrocution, electrical faults, and wildfires. These problems arise when animals cause phase-to-phase or phase-to-ground faults by coming into contact with energized components. Our product solutions are designed to reduce the risk of fires caused by wildlife and vegetation coming into contact with substations or overhead lines. Faults can also occur in cables and circuits within the electrical distribution network.

Wildlife can cause faults that disrupt the output of substations and interrupt the flow of electricity through power lines.

Insulating and isolating components help mitigate these active threats and reduce the risk of outages and fires related to wildlife interactions with energized lines. Overhead lines and power lines are supported by pylons or towers to maintain stability and safety. Investing in such protective measures provides a valuable return by safeguarding assets and communities from costly and potentially catastrophic wildlife interference.

Substation Outage Reduction

Reliability improvement is possible by insulating vulnerable assets in substations. Customizable TE Connectivity solutions are used around the world to effectively insulate thousands of substations every year from risk of outage caused by wildlife, vegetation, extreme weather events and accidental contact as well as reduce fire risk associated with animal electrocution. At the substation site, implementing proper safety measures such as fencing, signage, and access controls is essential to prevent unauthorized entry and minimize risks to both people and wildlife. TE Connectivity engineers solutions to enhance insulation clearances and exclude wildlife from high risk areas. Their products are easy to install and designed/manufactured to last the lifetime of your assets in the toughest environments.

Overhead and Wildlife Protection

Reduce outages and fire risk in overhead power lines while protecting endangered wildlife. Outage and fire risks can be reduced and eliminated with effective insulation of high risk elements of the overhead power line, which are typically supported by pylons and other structures. These insulation solutions are suitable for both upgrades and new construction projects, supporting eco-friendly and reliable overhead line installations in residential and commercial developments. TE Connectivity has insulated millions of miles and kilometres of bare conductor wire in distribution lines around the world. Insulating the wire in overhead power lines is essential for preventing wildlife-related outages. Their raptor covers, fuse cut out covers, re-closer and distribution covers protect pole mounted equipment from accidental and momentary contact from nesting and perching birds and storm debris. Most can be installed on energized equipment and are available in seamless one-piece designs for complete wildlife and vegetation management.
