In power distribution and transmission systems, maintaining safe and reliable insulation levels in cable entry boxes and terminations is paramount. The COMPAQ Elbow Terminal Protector (CRTP 1224) offers an advanced insulating solution designed specifically for environments where phase-to-phase clearance is minimal, posing a high risk of air flashover due to insufficient insulation. This whitepaper explores the key features, benefits, and applications of the CRTP, focusing on how it addresses common challenges in cable entry systems and enhances operational safety.

Key Features and Benefits of the COMPAQ Elbow Terminal Protector (CRTP)

• 1. Robust Insulation & Flashover Protection
• The CRTP provides a reliable barrier against phase-to-phase flashover risks in cable entry boxes. This is particularly crucial when dealing with limited phase-to-phase clearance. By acting as a robust insulator, the protector prevents flashover, ensuring the longevity and safety of the electrical system.
• 2. Superior Material Composition
• Made from specially formulated EPDM or Silicone rubber, the CRTP is engineered for high performance. This material offers exceptional UV resistance, track resistance, and mechanical strength, making it highly durable and effective even under harsh environmental conditions. The superior insulation properties of the CRTP ensure consistent performance in protecting electrical connections.
• 3. High Dielectric Strength
• With a dielectric strength of 15kV/mm, the CRTP offers exceptional electrical insulation, ensuring that the cable entry points remain safe and fully operational, even in high-voltage environments.
• 4. Quick & Easy Installation
• The CRTP is designed for easy, quick installation due to its one-piece moulded construction. This reduces installation time and the need for complex procedures, providing cost-effective solutions for contractors and operators.
• 5. Reusable & Cost-Effective
• Unlike traditional insulation systems that require frequent replacement, the CRTP is reusable, making it a long-term, cost-effective solution. It is designed to withstand the test of time and can be safely reinstalled during maintenance or upgrades.
• 6. Prevention of Animal-Related Incidents
• The CRTP provides a protective barrier against animals, including reptiles and birds, which can cause damage or short circuits when they come into contact with exposed electrical components. This added layer of protection enhances the safety of personnel and equipment.
• 7. High Operating Temperature Tolerance
• The CRTP is rated for continuous operation at 90°C with an emergency overload temperature of 130°C for up to four hours, ensuring that it performs optimally even in high-temperature environments.

Applications of the COMPAQ Elbow Terminal Protector

The CRTP is a versatile product that can be applied in various scenarios to enhance insulation and safety in cable entry systems. Below are some of the key applications:

• 1. Improvement of Insulation Levels in Air-Insulated Boxes and Panels
• COMPAQ Elbow Terminal Protector is ideal for enhancing the insulation levels of live parts in air-insulated boxes and panels. By preventing flashover and providing reliable insulation, it improves the overall safety and efficiency of power distribution systems.
• 2. Transformer Bushings
• COMPAQ Elbow Terminal Protector is suitable for transformer bushings with diameters ranging from 46mm to 56mm, providing effective insulation and preventing flashover in critical transformer components.
• 3. Ring Main Units (RMUs)
• Designed to seamlessly fit Ring Main Units (RMUs) with C-type bushings, the CRTP is perfect for RMUs operating with phase-to-phase clearance of 95mm and phase-to-ground clearance of 60mm. It provides optimal protection against flashover and enhances the system's operational reliability.
• 4. MS Boxes and RMU Chambers
• The CRTP is also applicable in MS boxes and RMU chambers, where it helps to maintain the integrity of the electrical system by preventing incidents caused by insufficient insulation or exposure to environmental risks.
