PURPOSE: A cable support device for transmission and distribution is provided to improve installation stability by attaching a friction pad in a light arm mounting groove and a pole mounting groove. CONSTITUTION: Two upper fixing units and two lower fixing units(120) surround a pole(10). Front and rear fixture connectors(130,140) are installed between the upper fixing unit and the lower fixing unit. Two bidirectional bolts(170) connect the front and rear fixture connectors. The upper and lower fixing parts connect the front and rear fixture connectors to the upper and lower fixing units respectively. A bolt connection unit rotates two bidirectional bolts at the same time. A friction pad is attached to first and second pole mounting grooves and first and second light arm mounting grooves of the upper and lower fixing units. The friction pad is made of the insulation material. |
