Protective Helix (S)
01 — Overview
3 sets × 5 rodsØ 3.2 mm1400 mm
- Code
- SYN-T1-PHS
- Type
- Type-I — Helix type (Heavy duty)
- Drawing
- TEC GR 11.10
Three sets of five aluminium alloy rods, preformed to a spiral that matches the cable diameter, applied circumferentially so they cover the total surface of the cable beneath the suspension fitting. Applied without excessive clamping pressure at any point — the load spreads along the lay rather than concentrating.

04 — Why it's built this way
- Ball-ended so application never catches the jacket
- Marked at the centre of its length for setting out
- Elongation on 200 mm: 7% minimum as wire, 4% minimum formed
- Colour-coded tag identifies the cable diameter it is cut for
