## Summary description

Prolech large connector sleeves for electrical conductors, size range 1.0–2.5 mm², blue color, pack of 100 pieces. Designed for joining and insulating flexible and solid copper wires within the specified cross-section range. Suitable for household and light industrial wiring, repairs, and maintenance where secure mechanical and electrical connection is required.

## Long description

Prolech large connector sleeves in blue are insulated crimp connectors designed for joining flexible and solid copper conductors with cross-sections from 1.0 to 2.5 mm². Supplied in a pack of 100, these sleeves provide a compact and reliable method for creating mechanical and electrical continuity in household and light industrial wiring, repairs, and maintenance tasks where a simple insulated connection is required.
Advantages
These connector sleeves combine an insulated outer sleeve with an inner conductor contact area shaped to accept stranded or solid copper wire within the specified size range. The insulation reduces the risk of short circuits and provides basic mechanical protection, while the standardized dimensions allow consistent crimping with common hand crimp tools. Supplied in a 100-piece pack, they offer a cost-effective inventory for repetitive installation or repair jobs.
Suitable for
 Joining flexible (stranded) and solid copper conductors 1.0–2.5 mm²
 Domestic electrical repairs and appliance wiring
 Light industrial control panels and wiring harnesses
 Temporary or permanent connections in renovation and maintenance work
Key specifications
 Conductor cross-section compatibility: 1.0–2.5 mm²
 Material: copper contact area with insulated sleeve
 Color: blue (insulation)
 Pack quantity: 100 pieces
 Intended conductor type: solid and stranded copper wire
How to use
Strip the conductor insulation to the appropriate length so the bare wire fully enters the metal contact area. Insert the stripped conductor into the sleeve until it seats against the inner shoulder. For a reliable connection, crimp the metal contact area using a compatible crimping tool sized for 1.0–2.5 mm² terminals; ensure the crimp is firm and the conductor cannot be pulled free. After crimping, visually inspect the sleeve to confirm insulation integrity and that no bare conductor is exposed beyond the insulation.
Usage recommendations
Use hand crimping tools matched to the sleeve size and avoid repeated bending of the conductor at the crimped joint. Select the correct sleeve size for the conductor cross-section to maintain electrical continuity and mechanical strength. For circuits carrying significant current or for safety-critical installations, follow local electrical codes and consider professional installation or further protective measures such as heat-shrink tubing or additional insulation.
