Comme nous le savons, les isolateurs haute tension doivent être soumis à un test de charge de rupture mécanique, et lorsque nous mentionnons « test en position verticale et horizontale », cela se réfère davantage à l’isolateur de suspension, l’isolateur de tension, le post-isolant et l’isolateur à broches. Les isolateurs de suspension et de tension sont normalement […]
Embout d’extrémité d’isolateur ferroviaire du marché indien Les raccords d’extrémité de l’isolateur composite en silicone pour la traction aérienne de 25KV ferroviaires ont des exigences spécifiques. Les raccords d’extrémité doivent être en fonte à graphite sphéroïdal de grade: 400/15 de IS: 1865-1991 ou raccords en acier forgé selon BS-970 (partie II). L’approbation de l’essai de […]

Qu’est-ce que la machine d’essai universelle? La machine de test universelle (UTM) est une machine de test spécialement conçue pour les tests multifonctions. Il est appliqué aux tests de matériaux composites métalliques, non métalliques, dont la fonction de test comprend, mais sans s’y limiter, les tests mécaniques courants comme la tension, la compression, la flexion, […]
What is crimping machine? Crimping machine is a kind of machine used to crimp the bottom flange of high voltage insulators in insulator production. With high pressure from hydraulic power force, crimping machine press the metallic flange from all direction and make the metal fittings (flange) well attach the core of composite insulators. Crimping machine is also […]
What is composite insulator? Composite insulator is also called polymeric insulator. It is developed after toughen glass insulator and ceramic insulators, whose main insulation structure is consist of a fiber glass core (rod) and silicon housing and sheds. One both side, 2 metallic fittings are installed on each side with crimping technics. These 2 metal […]
THE INSULATOR ROD SANDING MACHINE (FRP SANDING EUQIPMENT FOR PRODUCTION OF INSULATORS) GENERAL INTRODUCTION Like its name, insulator rod sanding/grinding machine is designed and developed for electrical polymeric long rod insulators and pin type insulators. These 2 types of electrical polymeric insulator (with another name composite insulator) is made of a fiber glass core in […]
What is porosity testing machine? The porcelain shell porosity testing machine is mainly applied for testing the porosity of the porcelain insulator shell. Porcelain insulator tester, porcelain insulator testing machine, ceramic insulator testing machine,ceramic insulator tester,disc insulator tester Why do we need a porcelain porosity testing machine? To ensure the desired performance of an electrical […]
This polymer housing tightness testing machie, also known as boling test machine is designed and developed for composite insulator (also called polymeric insulator). In international electrical standard (IEC61109 insulators for overhead lines – composite suspension and tension insulators for a.c. systems with a nominal voltage greater than 1000V – definitions,test methods and acceptance criteria) for […]
What is « Insulator bending & torsion resistance testing Machine »? The bending torsion testing machine is mainly applicable in the mechanical bending (cantilever) and torsion test for post type insulators and pin type insulators with material of porcelain and polymer. As it is required in IEC standard and ANSI standard, porcelain post insulators for subsation and overhead […]
