Abstract
Master valve and cable hanger system for deploying and making electrical connection to an electric submersible pump. A landing for the cable hanger (50) is in the through bore below the valve closure element. The landing has a seal area and a bore transverse to the through bore penetrating into the seal area for allowing electric connection to the pump. The cable hanger has a seal section having longitudinally spaced apart seals engageable with an interior of the seal area, electrical contacts disposed between the seals, and a lockdown profile. Flow ports are arranged to bypass seal area and seal section. A blanking plug (58) is disposed in the transverse bore to seal the seal area prior to insertion of the cable hanger.
