Innovative Technologies. Trusted Performance.
This electrical equipment integrates insulation and mechanical support functions, primarily used to fix conductors and provide electrical insulation in overhead transmission lines. It is commonly utilized in narrow corridor redevelopments and capacity-upgrade projects for existing lines.
A pin composite insulator consists of a steel cap, a steel pin, a core rod, and a silicone rubber shed housing. Widely used in urban and rural overhead distribution lines, it effectively enhances line insulation levels and operational safety.
AC/DC long rod-type suspension composite insulators consist of end fittings, core rods, silicone rubber sheds, and grading rings. They overcome the limitations of traditional glass and ceramic insulators in terms of pollution resistance, mechanical strength, weight, etc., and have become key components for ensuring the safety of power transmission in modern power systems.
