The Paprsky Trefoil Clamp is a robust cable-management solution designed to securely hold three single-core power cables in a trefoil configuration. Its precision-engineered geometry helps control electromechanical forces generated during short-circuit conditions while supporting efficient, organised installation in utility and industrial power systems. Constructed from durable non-FR polymer, the clamp provides stable cable containment for copper and aluminium conductors used in substations, transmission infrastructure, renewable-energy projects, and high-current distribution networks.
