3M Cold Shrink Insulator 8429-18, Tape/Wire/UniShield Shielding, 1 kV, Standard

3M Cold Shrink Insulator 8429-18 - Cold Shrink Connector Insulator for Electrical Wire & Cable The 3M Cold Shrink Insulator 8429-18 is part of the 3M Cold Shrink Connector Insulators 8420 Series, designed for primary electrical insulation of solid dielectric (rubber and plastic) insulated wire and cable splicing rated up to 1000 V. Utilizing 3M's proprietary cold shrink delivery system, these insulators are supplied prestretched on a removable core for efficient and easy installation. Once positioned, removal of the core allows the insulator to shrink into place, forming a moisture-tight seal. This product is suitable for electrical distributors, lighting solutions providers, wire and cable applications, and switchgear suppliers requiring durable insulation and environmental sealing for low voltage splices.
