Introduction
The purpose of these instructions is to provide
a procedure for the repair or modification of
RAYCHEM Copper and Alloy 825 sheath mineral
insulated (MI) heating cables manufactured
by nVent. They must be carefully followed to
ensure that the MI cable performs safely and
as intended.
During the installation of MI cables or during
plant maintenance processes, the cables are
occasionally damaged, cut or broken. It is usually
impractical to remove these cables and return
them to the manufacturer for repair. The field
repair of these cables is therefore, the only
feasible alternative.
The successful repair or modification of
these cables is a specialized procedure, and
as such, only qualified personnel at industrial
establishments, with the necessary competency,
are permitted to repair or modify MI heating
cable sets. Where the work involves a change to
the existing design, participation in the redesign
is required by the manufacturer; or alternately,
the design may be carried out by a professional
engineer using design tools provided by the
manufacturer.
For assistance, technical support, or other
information regarding the repair of RAYCHEM MI
cables, please contact your nVent representative
or nVent directly.
