Need marine type cable

[Ainsley Whyte]

I am running a cable to supply 460vac on a doc where ships are anchored. I would need some advice on the type of cable that can be used. What type of cable they usually used for this purpose in the marine industry?

I used type W and type G

Here's a whitepaper (well more of a marketing sell sheet) discussing this application and suggesting types W and G as oldsparky52 has

You would have to talk to an electrical wholesale distributor that carries General Cable brand, you're not going to get anywhere trying to talk to them directly. I don't know how buying things in Jamaica works.

Here is a place (no affiliation, just a customer) that sells these cables to give you an idea of price. Understand that their prices are lower than what can be had locally, especially compared to somewhere like Jamaica with the shipping cost involved. Don't use these numbers in a budget and expect to be able to get the product locally for the same cost.

No more suggestions, most places that sell this material don't post their prices. Talk to whatever supply house you get your material from.

And it is simple a type w or g general cable what's the difference of these cable

 

[Todd0x1]

General Cable is the name of the manufacturer. Other companies make these cable types too but general is the most common. Type G has extra ground wires and can be more rugged than W.

Interesting, I felt it was the other way around.

When I first started using W cable, it was a lot more rugged than a couple of years later. I think (but can't prove) that there is a "mining" grade of W and an "industrial" grade of W. I think the "mining" grade was phased out. I have no proof of this and I'm talking early 2000's.

One of the most important differences is if you want 2 hots, 1 neutral, 1 ground in a #2 wire size, you order a 2-4 W cable or a 2-3 G cable. The ground is understood in the G cable.

Try Anixter for pricing. https://www.anixter.com/en_us/servi...nd-cable/mining-cables.html?term=type g cable

I'll probably get blasted for this but about 20 years ago I needed to wire up a 460 volt 25 HP aeration pump on a lake. Needed about 200 feet of cable and couldn't find it anywhere without buying at least 1000'. I ended up using submersible well pump cable and the inspector signed off on it. Still working OK today.

Fortunately these days its possible to buy exact footage of pretty much anything at the same price as full roll.

There are definitely different grades of type W. The Carol Super Vu-Tron seems to be the most rugged of the normal rubber ones. Then there is type PPE which is a thermoplastic based equivalent which ranges from not rugged to nearly indestructible (like the polyolefin based cable from Philatron, super rugged but $$$$ and long leadtimes)

I have found that wireandcableyourway.com to be a good place for small quantities. Nice web site and easy to business with.

Anybody know how they prevent the water from wicking under the insulation and eventually ruining the cable?
Maybe each conductor is individually coated so the cable resists the water for a longer time?
And a "failure" means the conductors break rather than bend even on large radius bends, or the insulation fails a Megger test?

Water from where? Are you referencing the terminations?

Keep the terminations above the water line and don't damage the jacket when installing.

 

[WasGSOHM]

Yeah.
So for this cable I guess the insulation is especially impermeable to even salt water.
I only work with Romex, lamp cords, and salvaged power cords.

Referring to type "S" and sub-types (footnote in table 400.4)
"Cords that comply with the requirements for outdoor cords and are so listed shall be permitted to be designated as weather and water resistant with the suffix “W” after the code type designation. Cords with the “W” suffix are suitable for use in wet locations and are sunlight resistant."

Interesting that AFAICT types G and W aren't shown in table 400.4 as for wet locations (in the Use) column; only "Portable, extra-hard usage". A few spec sheets for W said "Suitable for shallow water immersion."

I'd generally go that if a jacket is oil and weather resistant, it's probably OK with water, too; still would like to see the mfg say so.
