Tubular Pre-insulated Terminals

pre insulated sleeve belongs to the category of cold-pressed crimp terminals and is classified as an electrical connector accessory, primarily used for electrical connections between wires and equipment. Its cylindrical tubular design enhances insulation safety when wires are closely spaced, prevents wire splitting, and optimizes ease of insertion. This product is widely used in low-voltage/medium-voltage power systems, industrial equipment, electrical control cabinets, and building electrical systems.
pre insulated junction sleeve The base material is made of tinned copper, offering excellent conductivity and oxidation resistance; the pre-insulation material is mainly polypropylene (PA66). The product complies with standards such as DIN46228-1990-09 and IEC 61238-1. Common models include TE Connectivity's KF-TE series (such as KF-TE0508 ​​to KF-TE16-14) and Vogt brand specifications with pin diameters of Φ1.4mm/1.7mm. The connection method is primarily crimping, requiring standard procedures such as wire stripping, sleeve installation, and conductor insertion.
