The utility model discloses a suspension type insulator, which comprises a silicone rubber umbrella skirt strip, wherein the length of the silicone rubber umbrella skirt strip is larger than or equal to 4 meters, an upper isopressing ring and a lower isopressing ring are connected to the two ends of the silicone rubber umbrella skirt strip respectively, and a locking pin is arranged on either the upper isopressing ring or the lower isopressing ring. In the suspension type insulator provided by the utility model, the silicone rubber umbrella skirt strip utilizes the upper and lower isopressing rings to form a whole insulator, and large and small umbrellas in the silicone rubber umbrella skirt strip are strung together through fiber-reinforced resin-based composite material; the height of a suspension type insulator exceeds 4 meters, which is equal to the height of more than 40 porcelain insulators or glass insulators overlapped, therefore under the condition that the quality levels are equivalent, the place where quality problems occur can only at the two end parts of the silicone rubber umbrella skirt strip, while more connecting points exist on more than 40 porcelain insulators or glass insulators overlapped, and as a result, the place where quality problems occur on the suspension type insulator is less, and the possiblity of line falling is lesser.
