Ranelast Silicone Sleeving Has Inherent Dielectric Strength Allied with Resistance to High
temperatures, High Voltage Ionisation, Arcing, Ultra Violet Light and Ozone Plus Carona Resistance Comparable with that of Mica, Make It Dependable in the Most Rigorous Electrical Applications Including Moisture Laden Conditions. It Will Continue to Insulate Even in Severe Vibratory
Conditions,After Reduction to Silicone Dioxide Ash By Direct and Rubber Flame Contact.
The Silicone Sleevings are Manufactured in Transparent or Opaque Versions. They Areavailable in Any Diameter and Wall Thickness, Any Length &any Colour.
Manufacturing Sleevings as Small as 0.20 Mm Wall Thickness is Rane's Forte. 0.20 Mm Wall Thickness is Rane's Forte. Procedure Right from the Stage of Raw Material, Formulation, Compounding & Mixing to Extruding Finishing and Physical Measurement. They are Rigorously Tested to the Most Punishing Requirements Subject to Ardorous Duties as per Standard B. S 2848 Type 5 & B. S G.i 98 Type 4 When Carefully Compounded and Extruded, It Gives Following Excellent Properties.
