Radpol insulated ferrule TOKSJ0020001001 AI 2x 2.5–10 mm² tinned copper tubular cable end

Radpol insulated ferrule TOKSJ0020001001 AI 2x 2.5–10 mm² tinned copper tubular cable end is a pair of insulated tubular ferrules designed for terminating stranded conductors with cross-sections from 2.5 mm² up to 10 mm². Each ferrule features a tinned copper tube that ensures good electrical conductivity and improved resistance to corrosion, combined with a colour-coded insulation sleeve for reliable mechanical support and safer insertion into terminals in panels, distribution boards and control cabinets.

Advantages

The tinned copper construction provides consistent low-resistance contact and reduces oxidation over time, while the tubular design ensures even deformation during crimping for a durable conductor termination. Insulation sleeves protect the exposed conductor end, reduce the risk of short circuits and facilitate cleaner, more repeatable crimps. The product is supplied as a matched pair for twin conductor termination and is suitable for both field and workshop use where secure, standardized cable ends are required.

Suitable for

• Terminating stranded copper conductors from 2.5 mm² to 10 mm²
• Electrical panels, distribution boards and control cabinets
• Industrial machinery and control wiring
• Field installation and maintenance work requiring reliable crimped ends

Key specifications

• Conductor cross-section range: 2.5–10 mm²
• Quantity per unit: two ferrules (twin configuration)
• Material of tube: tinned copper for improved conductivity and corrosion resistance
• Insulation: protective sleeve for safer terminal insertion and strain relief
• Type: tubular ferrule designed for crimping onto stranded conductors

How to use

Strip the conductor to the appropriate length, ensuring no stray strands are left outside the ferrule. Insert the stripped conductor fully into the tinned copper tube until it reaches the insulation sleeve. Use a crimping tool matched to the ferrule size and the conductor cross-section to compress the tube evenly, forming a secure mechanical and electrical connection. After crimping, verify the termination by a gentle pull test and inspect that the insulation sleeve covers the conductor insulation and that no bare strands are exposed.

Usage recommendations

For consistent results, use a calibrated crimping tool with dies suitable for 2.5–10 mm² ferrules and follow applicable installation standards. Avoid using the ferrule on conductors outside the specified cross-section range and store the product in a dry environment to preserve the tin coating and insulation integrity.
