Tykoflex T240 closures adapted for OPGW use have been the standard for several Nordic power companies for more than 20 years. For full information see Tykoflex Closures for OPGW and ADSS applications. One of the critical aspects of fibre in OPGW applications is avoiding harmful contact between fibres and metal tubing.
Tykoflex has developed a unique solution for this and a well proven working method along with technical innovations.
A frequent requirement for closures that are visible in open country is that they should be shotgun proof.
