IPX8 Gel-Filled Straight Joint, 4-Core 2.5-16 sq mm, up to 1 kV - Raytech Rapid Joint L10 (301098-004)

4-core cable 2.5-16 mm² (single-core 2.5-150 mm²), 180 x 60 mm. Raytech Rapid Joint L10 is a cylindrical, gel pre-filled straight joint for extruded-insulation cables up to 1 kV. Its two gel-filled half-shells close radially around the connected conductors, so the joint is quick to fit, sealed to IPX8 - fully submersible and suitable for underground use - and can be re-opened later, but only with a tool. Item 301098-004, list price Rs 4,494 per joint.

Raytech is an Italian manufacturer that specialises in gel-based insulation for electrical connections: pre-filled gel boxes and joints that are ready to use straight from the pack, and insulating gels and rubbers for filling joints, boxes and enclosures. Rapid Joint is made of self-extinguishing, flame-retardant material for cables working at 90 °C, with spacers that keep the joined conductors apart inside the gel.

Is this the right one for you?

Check these six things before you order:

• The cable has extruded insulation (for example PVC or XLPE) and is rated up to 1 kV.
• The copper conductors are within range for their number of cores: 1-core 2.5-150 mm², 2-core 2.5-25 mm², 3-core 2.5-16 mm², 4-core 2.5-16 mm².
• The conductors are copper - for aluminium, Raytech lists Rapid Joint L25 and L95.
• You will join the conductors with connectors that comply with EN 61238-1.
• There is room for the joint: 180 x 60 mm (length x diameter).
• The cable is unscreened and unarmoured - screened and armoured cables need a different joint.

Why choose it

• Pre-filled with gel - nothing to mix, pour or wait for: the joint is ready as soon as it is closed
• Radial closing - the shells close around the connected conductors, so there is no sleeve to slide over the cable first
• Tamper-resistant - re-enterable, but only with a tool
• IPX8 - fully submersible and suitable for underground use
• Flame retardant - self-extinguishing casing; no flame propagation to CEI 20-35, IEC 60332-1 and HD 405-1
• Spacers keep the conductors apart inside the gel
• Safe gel with no shelf life - not classified as hazardous under CLP and halogen-free

How it is installed

1. Prepare the cable ends and join the conductors with suitable connectors - for power cable, connectors that comply with EN 61238-1.
2. Fit the spacer so the joined conductors are held apart, and lay the joint in one gel-filled half-shell.
3. Close the second half-shell over it: the shells lock radially and the gel closes around the conductors and connectors. To re-open the joint later, use a tool.

Where it is used

• Repairs and extensions of buried 0.6/1 kV power cables
• Feeders to street lighting, pumps and outdoor equipment
• Cable runs in wet ducts, pits and flood-prone areas
• Solar plants and other infrastructure cabling
• Industrial plant cable repairs where a quick, cold-applied joint saves downtime
