Abstract
A conductor module (M) comprises a jacket (E) tightly accommodating, in the manner of tubing, at least two flexible conductors (C). The conductors (C) are coated with a small amount of oil (H) having a viscosity strictly less than 100 millipascal second (mPa.s) so as to allow control of the slippage of the jacket (E) in relation to the conductors (C) and longitudinal impenetrability inside the module (M).
Claims17
Conductor module (M) comprising:
- a jacket (E) tightly accommodating at least two flexible conductors (C), wherein said conductors (C) are coated with a small amount of oil (H) having a viscosity less than 100 millipascal second (mPa.s) at a temperature between 18° C. and 22° C. so as to allow control of the slippage of said jacket (F) in relation to said conductors (C) and longitudinal impenetrability inside said module (M).
Method of producing a conductor module (M) comprising a tubing jacket tightly accommodating at least two flexible conductors, the method comprising the following steps:
- coating the at least two flexible conductors (C) with oil (H) having a viscosity less than 100 millipascal second (mPa.s) at a temperature between 18° C. and 22° C.;
- and
- extruding the tubing jacket (E) around said conductors (C) such that the coated conductors are tightly accommodated in said jacket to control slippage of said jacket relative to said conductors and to prevent penetration of moisture inside said module.
