Waterproof Wire and Cable Material Structure

Almost all sheathing compounds, from PVC to polyethylene to Teflon, are at least waterproof, so they can get wet and then dry, and their cables may be fine. It really depends on how much time they spend in the water and what kind of exposure they may have. GRAND tells you about water-blocking materials and the associated need for waterproof cables.

The real problem is when the cables are in standing water that won't go away. Water is often referred to as the "universal solvent": given enough time, it will pass through anything. Water easily passes through polyvinyl chloride (PVC), which is the most common cable sheathing material. It can take weeks or months for a submerged cable with a PVC jacket to fail. The first step toward long-term water resistance is to use a better sheathing material, such as polyethylene (PE). This is more waterproof, especially if it is high-density PE, and can last for months or even years underwater.

But you can also take the additional step of specifying the cable with a "water barrier" layer. The first step toward long-term water resistance is to use a better sheath material, such as polyethylene (PE). This is more water resistant, especially if it is high density PE, and can last for months or even years underwater.

Water blocking mechanisms

There are two types of water barriers: dry water barrier and gel water barrier. Dry water barrier is another layer in the cable, under the sheath but on top of everything else. It is an impregnated cloth that is wrapped around the core of the cable. If there is a hole or cut in the jacket and water comes in contact with this layer, it will swell and hold back the water. Because it is just a layer of cloth, it has no effect on the performance of the cable or the performance of the connector. Simply cut off the excess layer and put on the connector as usual.

After stripping the cable, you must remove the gel before you can install the connector. You can use special wipes (such as alcohol wipes or citrus wipes) to remove the gel.

Grand Electronic Technology manufactures a wide range of waterproof cables, many of which you can find on our web page. Our webpage shows many of our waterproof cables, including signal cables, charging cables, charging ports, etc. It has both a high-density PE jacket and a gel barrier, providing us with the ultimate in long-term waterproof protection.

Cable Use

If the connector is not going to be used outdoors, then your waterproof cable must go into the building before it can be connected. There is another issue because many of these cables are not fire rated. the NEC specification is very clear that any installed cable must be fire rated, even if it is installed in conduit. Waterproof cables with a PE jacket do not have a rating. Suitable for outdoor applications, but not for indoor use. Please be aware of it before purchasing and ask your supplier for the appropriate standard.
