ANSI 54-2 porcelain strain insulatorStrain insulator: dead end or anchor pole or tower is used where a straight section of line ends or angles off in another directionThese poles must withstand the lateral (horizontal) tension of the long straight section of wireIn order to support this lateral load, strain insulators are usedFor low voltage lines (less than 11kV), shackle insulators are used as strain insulatorsHowever, for high voltage transmission lines, strings of cap-and-pin (disc) insulators are used, attached to the cross arm in a horizontal directionWhen the tension load in lines is exceedingly high, such as at long river spans, two or more strings are used in parallelSpecifications:Certifications: IEC/ANSI/GB/ISO 9001Can design and produce according to the drawingsSupply insulators with good serviceAttend 2007 Hannover exhibition, India electricity 2008 exhibition, 2008 Hannover exhibition, 2009 and 2010 Dubai Middle East electricity exhibitio
