A computer-controlled optical cable tension tester is a machine used for testing the tension of optical cables. 4) Load resolution: ±250000 yard,no stepping, no change in full scale,resolution unchanged. Each testing machine can be operated of all function which by. TESTRON TT-OFT Optical Fiber Cable Tensile Testing Machine designed for precise testing of optical fiber cables under tensile and crush conditions.
[pdf] Due to their exposure to the open air because of the cable trays, the wires contained within need a very durable outer covering. The regulations dictate that the cables must either be Type TC (also known as Tray Rated) or must be metal-armored (Type MC). It has a UL two hour fire resistive rating. In industrial establishments where conditions of maintenance and supervision assure that only qualified persons will service the installed cable tray system, the following cables may also be installed in ladder, ventilated-trough, or ventilated-channel cable trays: (a) Single conductor cable.
