What machines are needed for 11kV polymer insulator production line?

Polymer insulators are important electrical items in electrical power overhead transmission, distribution, and substation lines. They provide reliable insulation between cables and iron towers, or between conductors and connecting fittings like clamps so that the electricity can be transmitted safely. With the global growth of the electrical industry, more and more people smell the potential […]

Composite insulator (Polymeric insulator)

What is a composite insulator? The composite insulator is also called the polymeric insulator. It is developed after toughened glass insulator and ceramic insulators, whose main insulation structure is consists of a fiberglass core (rod) and silicon housing and sheds. One both sides, 2 metallic fittings are installed on each side with crimping technics. These […]

1.Scope and object of IEC61109:2008 INSULATORS FOR OVERHEAD LINES – COMPOSITE SUSPENSION AND TENSION INSULATORS FOR A.C. SYSTEMS WITH A NOMINAL VOLTAGE GREATER THAN 1 000 V – DEFINITIONS, TEST METHODS AND ACCEPTANCE CRITERIA

Scope and object This International Standard applies to composite suspension/tension insulators consisting of a load-bearing cylindrical insulating solid core consisting of fibers – usually glass – in a resin-based matrix, a housing (outside the insulating core) made of polymeric material and end fittings permanently attached to the insulating core. Composite insulators covered by this standard […]

Test of sheds and sheath material of composite insulator

Composite insulator’s shed and sheath are be made of high temperature vulcanizing (HTV) type silicone rubber, having silicone polymer content by weight 30% minimum. Alumina Trihydrate (ATH) is used as a filler. The filler is properly mixed with silicone compounds to ensure uniform distribution. The thickness of the sheath shall be a minimum of 3 […]
