Dweller of the Desert asked 22 questions in his post …

Middle East Query – 22 Questions.

In this first installment I address questions 1 and 2.

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.

Insulation:

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

e.   more.

Installations:

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.

Voltages:

a.   Secondary voltages;

b.   primary voltages;

c.    transmission voltages; and

d.   zero voltage optical cables.

Conductor stranding:

a.   Concentric (round);

b.   compressed; and

c.    compact.

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.
