• The metal-free cable is not susceptible to lightning strikes.

• Optical fibre cables can be installed in close proximity to electrical power lines and power installations without any interference from induced electric currents.

• Hydrogen generation caused by the corrosion of steel strength members is no longer a concern.

• The strength to weight ratio of FRP strength members from SPI far exceeds that of steel.

PRODUCT INFORMATION

Construction:

Based on a continuous process, SPI FRP strength members comprise fibre reinforcement combined with a thermosetting resin formed into rods of various diameters and specified lengths.

The standard construction is based on E-glass fibre reinforcement in a vinyl ester resin matrix.

Other Shapes:

Whilst round FRP rod is standard, the manufacturing process developed by SPI allows any shape of uniform cross section to be produced.

Diameters:

Normal range is between 0.4mm to 4.5mm. Other diameters can be produced on request.

Lengths:

Standard lengths are 26km (diameters less than 3.1mm) and 15km (diameters greater than 3.1mm). Lengths greater or less than these can be produced on request.

Coatings:

SPI FRP tension members can be supplied either coated or uncoated as required. Ethylene Acrylic Acid (EAA) is the standard coating used by SPI.
