Type—IHelix, Heavy Duty

Type-I accessories are the heavy helix range: preformed aluminium-alloy and aluminised-steel fittings that grip the cable along its length rather than pinching it at a point. Specified for spans carrying cable rated above 10 kN — typically 15 to 18.5 mm diameter on power line and rural alignments. Sixteen drawings in the GR, from the tension pole assembly down to the split pin.
