Contents I. Introduction
Polytetrafluoroethylene (PTFE) is the nozzle material of high voltage SF6 ac circuit breaker (HVAC). In order to improve are ablation resistance of nozzle material, different fillers can be added to PTFE like , BN and Mos2.

Abstract:
Electrical conduction properties of PTFE filled with 0.2 wt.% of MoS2 are investigated in view of its use in high voltage dc applications. Conduction currents were measured at temperatures from 25°C to 115°C and applied fields up to 60 kV/mm. Volume resistivity has been determined and the conduction mechanisms have been analyzed. After an “ohmic” behavior observed for fields lower than 20 to 30 kV/mm (depending on temperature), the current was found to be controlled by hopping and heterocharge-assisted Schottky injection.
