Why Are The Main Wire Specifications For Piercing Clamps Set In The Range Of 16–400 Mm²?

The wire piercing connector mainline range typically covers 16–400 mm². From a conductor compatibility perspective, the insulation piercing connector mainline range covers common aluminum/copper mainline sizes and meets the diverse needs of power distribution lines from small to medium-to-large sizes, a fact confirmed in the product specifications of multiple manufacturers. Regarding the mechanical piercing structure, when the mainline cross-sectional area is in the 16–400 mm² range, the piercing connector piercing blade, clamping mechanism, and insulating shell can be pre-designed as a unified structural module, thus achieving standardization in production, installation, and maintenance.
