nner that under normal conditions they will not slide along the line wire when subjected to an axial force of 50 Newton. They should (also having taken up any play) not rotate when subjected to torque of 0.1 Newton meters. The method used, however must not weaken the line wire.
After barbing the line wire shall be formed into coils of 68 1 turns each being approximately 1 meter in diameter. The adjacent turn shall then be clipped together with mild steel clips at intervals of approximatel
