Anchor is used for two ends of insulated bracket, it can prevent contact rail long rail move to two sides ununiformity, install the middle parts of long rail. Anchor force is supported by insulator or insulating bracket, keep the mid- point of expansion section. One place use two sets of anti-creep device . Connection of anchor and contact rail adopt standard fasteners bolts, nuts and washers. And material of type Ⅰ anti-creep device body is the same to that of contact rail,type Ⅱ anti-creep device body made of cast stainless steel.
