Middle East Query – 22 Questions.
In this first installment I address questions 1 and 2.
1. What kinds, types, and sizes of power cables can be injected?
Cable types and addressable problems:
a. Power – water trees, oxidative degradation, strand-corrosion, water intrusion;
b. electrical communication (twisted pair and control cables) – water intrusion, cross-talk, conductor corrosion, battery;
c. fiber optic – water intrusion;
d. umbilical cables containing all of the above including hydraulics – see addressable problems in a-c;
e. marine cables, large vessels.
a. HMWPE (high molecular weight polyethylene);
b. XLPE (cross-linked polyethylene);
c. TR-XLPE (tree-retardant cross-linked polyethylene);
d. EPR (ethylene-propylene rubber in all its various colors and flavors); and
a. Direct buried;
b. cable in conduits and ducts;
c. submarine cable;
d. cable in trays (inside and outside)
Conductor sizes: 30 mm2 to 1000 mm2.
a. Secondary voltages;
b. primary voltages;
c. transmission voltages; and
d. zero voltage optical cables.
a. Concentric (round);
b. compressed; and
2. What kinds, types, and sizes of power cables cannot be injected?
Solid and strand-blocked power cables cannot be injected. Gel filled communication cables cannot be injected.
