TANZANIA - Avoid sagging in distribution power cables
TANZANIA - Avoid sagging in distribution power cables
(OP)
Good afternoon,
we are Devergy, a utility installing solar microgrids in rural areas of developing countries.
We have an issue with the cables that we currently purchase in Tanzania.
Problem:
When we install the aerial distribution lines, after some time, the cables between two poles, sags under its own weight, and the intense sun, reducing the the clearance from the ground.

Current material used:
We currently use PVC insulated cables, with a 2x1.5mm2 copper stranded conductor (see picture). These cables are manufactured according to our specifications, hence we can request design changes. We distribute 24V DC electricity.

Solutions:
- Use a support metal wire between the two poles (anybody knows the engineering name for it?)
- Request the cable manufacturer
-- to add a metal support wire inside the cable itself
-- to replace the PVC outer jacket with another insulation jacket (e.g. XLPE or EPR)
Any take on the solutions described above? any good solution you'd like to suggest?

Is the wire Hard Drawn?
Since it's low Voltage and insulated why don't you just run it on the ground

The micro grid must be pretty micro. 1.5 mm2 cable will only handle about 5A, or 120 watts at 24 vdc.
