Composite / Polymer Long Rod Insulators & Suspension Insulators

Features

Composite Long Rod Insulator and Suspension Insulators for Transmission Line are operational under varied ranges. In the HV segment, it ranges from 66 to 330 kV, in the EHV range from 400 to 765 kV and in the UHV range insulators are operational at 800 kV HVDC (420 kN), 1200 kV AC/320 kN (the highest operating voltage in the world). Composite Long Rod Insulator and Suspension Insulators are designed for operation in high corrosion areas. The elastomeric insulation is made of silicone rubber of the highest consistency type HTV from Dow Corning and the insulating core and terminals is a fiberglass composition of the ECR type, which provides great mechanical resistance to traction. The connecting horns can be made of galvanized steel or stainless steel.

The application of the insulators is in all environments including severely polluted coastal areas, hilly terrain, snowy locations, severe wind and desert pollution proving the wide worldwide acceptability. Besides, these insulators are provided with different specifications to choose from, as per IEC 61109 / ANSI C29.12 standards.

And have features of excellent leakage current control, resistance to severe environmental pollution, good resistance to fungus formation, UV resistance, ease and minimum cost of installation, silicone rubber insulation with a high level of resistance to tracking, brittle failure proof, light weight and easy to install.

Composite Pin Insulators

Features

The Composite Pin Insulator has a high resistance to bending, shock resistance and anti-explosion performance. The inner insulation is reliable and the weight is light. The Composite Pin Insulators are intended to be mounted rigidly on a supporting structure by means of a pin passing up inside the housing which is molded or cast by circumferential crimping process.

Product Properties

• Voltage : 10kV - 35kV
• Mechanical load : 5kN & 10kN
• Creepage distance : 180mm - 1116mm
• Diameter of screw : 16-22mm
• Standard : IEC 61109, BS, ANSI

Composite Railway Insulators

Features

The Composite Railway Insulators are available in range of 25 kV for Railways in 9 Tonne, Stay arm hook & Bracket tube configurations. The use of Polymeric/Silicone Rubber base insulators have several advantages over the conventional ceramic insulators e.g. light weight, unbreakable, hydrophobic, resistant to ozone & UV radiations, resistant to earthquake shocks, self cleaning properties & resistant to vandalism. These Composite Railway Insulators are manufactured as per IEC 61109 & RDSO standards.

The Composite Railway Insulators is used in tunnels of electrical railway under severe conditions. The (Silicon Rubber) Composite Railway Insulators can effectively prevent pollution flashover outage and free from cleaning maintenance work with a very small size, they can be substituted by porcelain or glass insulators in case of small tunnel space. The end fittings are crimped onto fiberglass rod with crimper. The connection location between end fittings & rods is fused with sheds housing by the overall high temperature vulcanized silicone rubber injection molding as it could minimize the interface.
