Problems solved by technology

Composite insulators use silicone rubber shed sheath as the outer insulation, but the use of silicone rubber to make the shed still cannot get rid of the relatively soft nature of silicone rubber. If it is operated outdoors for a long time, the shed is easily damaged, which will lead to a decrease in insulation performance.

Abstract

The invention discloses a base material of an enhanced type shed sheath and a preparation method of the shed sheath, relates to the field of shed materials of power transmission line composite insulators, and aims to solve the problems that the conventional shed material is low in strength, and the insulating property of the conventional shed material is obviously reduced along with the running time. The base material of the enhanced type shed sheath comprises the following components in parts by weight: 20-40 parts of isoprene rubber and / or butadiene rubber, 5-10 parts of an ammonium phosphate flame retardant, 8-12 parts of magnesium hydroxide, 3-8 parts of an antioxidant 1010, 3-12 parts of a sensitizer, 2-7 parts of a stabilizer, and 5-20 parts of filler silicon dioxide or aluminium trioxide. The shed sheath prepared by the invention has better mechanical property, insulating property and flame retardant property.

Description

technical field [0001] The invention relates to a shed material for a composite insulator of a power transmission line, in particular to a reinforced shed sheath base material suitable for an ultra-high voltage transmission line and a preparation method for the shed. Background technique [0002] The insulator is one of the main components of the transmission line. Its function is to support the wire, prevent the current from returning to the ground and increase the creepage distance. Its performance has an important impact on the safe and stable operation of the power grid. Line insulators are mainly divided into three categories: composite insulators, ceramic insulators and glass insulators. Composite insulators use silicone rubber shed sheath as the outer insulation, but the use of silicone rubber to make the shed still cannot get rid of the relatively soft nature of silicone rubber. After long-term outdoor operation, the shed is easily damaged, which will lead to a decre...
