Characteristics：
1. The stainless steel tube that houses the fibre has a high tensile strength and a high crush resistance in 

order to provide an effective protection. The fibre is mechanically decoupled from other component parts of 

the cable structure in all expected conditions of use. This ensures successful operation during the life 

expectancy of the cable
2. TFO strives for compact and lightweight OPGW designs in order to reduce influences of wind and ice, and 

to minimize loading of the towers of the power line grid
3. By protecting the opticing fibre using a gel filled stainless steel tube which has a high radial thermal 

resistance, OPGW temperatures up to 300℃ can be allowed in a single phase short-circuit situation
4. TFO realizes high strength / small diameter OPGW designs by selecting the right type and size for the 

aluminium cladded steel wires in the center of the structure
5. TFO strives for designs with properties that maximally approach those of conventional earth wires in 

order to meet short-circuit requirements and to ensure secure operation of the power line circuit
