Product Introduction

Epoxy's Electric/Eleetronic Insulation Rod

Epoxy Fiberglass Rods are widely used in composite insulator of the silicone rubber、post、cross arm 、drop switch、disconnecting switch、post of the electrical a railway etc ,THIM can produce epoxy pulling Φ1-4m rods are used in optical cable.
The products are conformed with JB5892-91,IEC standard ralated .
Products Demand
1. The core rods length are fabricated with costomer demand,length tolerance egual to or less than ±1mm.
2. No crack fault trace on inside and exteriority don,t allow gum desposit.Hue per rod is light yellow and light green which is uniform.
3. Can use saw,milling,knife plane,drilling,lathe grinding etc for machining.
4. Internal screw can use tap to riffing ,external screw-thread,can apply grinding ,
But can,t withstraw the larger load.Main technique parameter as follows.See table.
