Coats Glasmo SM VO is an oval shaped glass fibre strength member engineered yarn for use in telecommunication cables. Coats Glasmo SM VO provides linear strength and stability and can be used to promote adhesion between the glass fibre components and cable sheath without the need of an IR pre-heating process.

The improved strength of the glass fibre means that cables can be redesigned to be smaller in size, saving cost.

Principais utilizações

  • Strength member for drop wire cables including copper, fibre optic, shielded and coaxial cables

Recursos e benefícios

  • Glasmo SM VO can be a fit for purpose coated strength member which eliminates the need of a preheating process to secure adhesion to the sheath and glass fibre components. This allows for a more streamlined production process which will save cost.
  • Our coating processes increase the strength of the glass fibre and means that cables can be redesigned to be smaller in size saving PVC material sheath cost, whilst still meeting strength specifications.
  • Produced to customer specifications and comes with the back-up and support of Coats global network.
