Abstract: An electric vehicle charging connector (100) comprising an external enclosure (104), an inner enclosure, and a compartment (102) for power contacts. The external enclosure (104) encloses an inner enclosure (103), and is configured to receive and guide a cable (101) from a back end (111) of the electric vehicle charging connector (100) to the inner enclosure (103) at a front end (113) of the electric vehicle charging connector (100). The inner enclosure (103) comprises the compartment (102) and is configured to provide the cable (101) to the compartment (102). The electric vehicle charging connector (100) further comprises a heat pipe (106) comprising an evaporator (107), and a condenser (109). The evaporator (107) is attached to a heat source in the compartment (102) inside the inner enclosure (102), configured to conduct heat from the heat source via the external enclosure (104) to the environment, wherein at least a part of the heat pipe (106) is arranged outside the external enclosure (104).

Abstract: The present invention refers to HV apparatus, in particular a HV dry current transformer, insulated with an insulating gel, or a voltage transformer, insulated with an insulating gel. The dry HV current transformer comprises at least two electrically conductive elements i.e. a head transformer cover, a head housing base, a core casing and a primary conductor. In the dry HV current transformer at least one of the electrically conductive elements has a coating made of solid insulating material separating the surface of the conductive elements from the insulating gel and adapted for limiting the electron emission from the conductive elements into the insulating gel. The voltage transformer comprises a bottom external housing, a bottom support flange, a core. In the voltage transformer at least one of the electrically conductive elements has a coating made of solid insulating material separating the surface of the conductive elements from the insulating gel and adapted for limiting the electron emission from the conductive elements into the insulating gel.
