As the further improvement of above-mentioned technology, described sealing ring uses super heated rubber O-ring seals.
As the further improvement of above-mentioned technology, described main body uses the design structure of underpass type.
As the further improvement of above-mentioned technology, described dome platform and recessed round platform are respectively equipped with 3.
As the further improvement of above-mentioned technology, described groove and boss are respectively equipped with three.
As the further improvement of above-mentioned technology, described lower body part is provided with well head main body lock sleeve.
Compared with prior art, the beneficial effects of the utility model are: dome platform matches with recessed round platform, adds electrode Creep age distance, improve insulating properties, make between electrode (relative phase) and electrode over the ground (relatively) ability of proof voltage carry Height, groove and boss match, and after ground quarter bend plug inserts cable penetration device main body, the boss of ground quarter bend plug is certainly So insert in the groove of main body, make cable penetration device main body be relatively fixed with ground quarter bend plug, will not be cable penetration device Three electrode wires in main body are twisted bad, it is ensured that the electric conductivity of cable penetration device connecting portion, ground quarter bend plug anterior with And main body upper end is equipped with fin, the heat in making well and in penetration device discharges at this, and good heat dissipation effect, so that well head is electric Between cable penetration device main body and ground quarter bend plug, the temperature of connecting portion is substantially reduced, and is conducive to improving cable penetration device even Connecing electric conductivity and the sealing property at position, be provided with sealing ring in main body, sealing ring uses super heated rubber O-ring seals, uses Multiple-sealed and dual gauge O combination sealing mode so that the sealing property under high temperature and high pressure environment is reliable, and main body includes Portion's main body and sub-body, be applied to heavy crude heat extraction and handle up in exploitation, can reuse, improve service life, it is possible to be big Width reduces thermal recovery cost for oil production, can meet power cable under high-temperature and high-pressure conditions, convenient, safe and reliable through oil well, It is effectively improved the power cable sealing property from wellhead traversing and reliability, it is therefore prevented that letting out of corrosivity and harmful gas Leakage, safety has obtained sufficient guarantee.
