Patent
·
OSTI ID:5618739
An improved cable feed-through apparatus and method for wellheads including a unitary shell having a plurality of knock-down components therein. A plurality of parallel spaced conductors are inserted through rigid spacing and compression rings with upper and lower exposed ends for providing coupling to electric feed cables. The conductors are insulated throughout by resilient sleeves which are removably mounted in the shell. When assembled, as the shell is threaded into a hanger of a well casing head, the resilient sleeves are compressed and forced together to form a pressure-tight, insulated cable feed through device. 11 claims.
