PURPOSE: An angle adjustment type two lead-in and cut out switch complex crossarm structure is provided to reduce investment cost, to reduce an amount of work of a field worker, to reduce maintenance cost, to improve the beauty of the city and to prevent negligent accident by installing two extra-high voltage customer points of responsibility division in one electric pole to supply two customers and by installing one extra-high voltage customer point of responsibility division, one pole transformer and one cut out switch in one electric pole to supply one existing extra-high voltage customer and low voltage customers. CONSTITUTION: A complex crossarm having a support band(1) fixed to an electric pole, a support(2) connected to the support band, an insulator(3) and et cetera installed across the support and a cut out switch(COS) installed includes the support forming an H shape support in which an upper and lower supports(2a,2b) are connected via vertical bar(5), a C shape crossarms are engaged in a specific angle in the both sides based on the front end of the upper and lower supports and angle adjustment bolt holes formed in a C shape crossarm, and respective C shape crossarms and the upper support are connected via tensile angle adjustment arm ties. |
