It seems like you’re describing a key for the tip of an insulator, which might be used in electrical or construction contexts. Here’s a description: The key for the tip of the insulator is a specialized tool designed to fit onto the end or tip of an insulator, typically used in electrical installations or construction projects. It is specifically crafted to match the dimensions and shape of the insulator’s tip, ensuring a secure and precise fit. This key is typically made of durable materials such as metal or hardened plastic to withstand the rigors of use and provide long-lasting reliability. It may feature a hexagonal or square-shaped head measuring approximately 12 mm in width, allowing it to engage with the corresponding shape of the insulator’s tip. The key serves several purposes, including installation, adjustment, or removal of the insulator. It provides a firm grip and leverage, enabling the user to tighten or loosen the insulator securely without causing damage to the insulator or surrounding components. Overall, the key for the tip of the insulator is a practical and indispensable tool for professionals working with insulators in various applications, ensuring efficient and precise handling for optimal performance and safety.
