Problem/Challenge

Substations require internal fencing systems that prioritise both safety and durability. Traditional steel fencing, while commonly used, presents inherent risks in high-voltage environments due to its conductive nature. In the event of electrical faults, steel can carry current, creating a serious hazard for personnel and potentially compromising equipment.

In addition to safety concerns, substations often operate in environments where exposure to moisture, chemicals, and fluctuating conditions can accelerate corrosion. Steel fencing is prone to rust and structural degradation over time, leading to increased maintenance requirements and higher lifecycle costs. The client needed a solution that would mitigate electrical risk, withstand harsh conditions, and remain reliable with minimal upkeep.

Solution

Relinea installed GRP palisade fencing to directly address these challenges, providing a solution that combines safety, durability, and ease of installation. As a non-conductive material, GRP eliminates the risk of electrical current transfer, making it inherently safer for substation environments. Its non-conductive nature also means the fencing does not need to be earthed, simplifying installation and reducing associated costs.

The fencing system comes pre-assembled and is easily installed, with no welding required. This removes the need for bulky welding equipment and hot works permits, improving efficiency and safety during installation. Its lightweight design means that no heavy lifting gear or specialist equipment is needed, allowing a two-person team to complete the installation quickly and effectively.

GRP palisade fencing panels provide a long-lasting, durable alternative to steel. Unlike metal, they are non-rust and corrosion-resistant, ensuring performance is maintained even in harsh or chemically aggressive environments. The chemical-resistant resin allows the fencing to be used in demanding conditions such as substations, coastal locations, rail infrastructure, and industrial facilities.

In terms of performance, the panels offer high energy absorption, meaning they can withstand repeated impacts without permanent damage. This contrasts with steel fencing, which is more likely to buckle under force. Additional benefits include being radio frequency transparent and sound absorbing, making the fencing suitable for environments where signal transmission or noise reduction is important. GRP is also non-magnetic, further broadening its suitability across specialist applications.

Overall, the installation in Kilkenny demonstrates how GRP palisade fencing delivers a safer, more resilient, and cost-effective solution compared to traditional steel, meeting the complex demands of modern substation infrastructure.
