How To Choose Harsh Environment Cabling Cable? These Points Should Be Kept In Mind

Regarding Harsh, that is, the kind of cable used in particularly bad places, many of the brothers who are engaged in engineering are actually confused and don’t know what to choose to be the right one. This kind of cable is completely different from the ordinary cables we usually use for home and offices. It has to withstand the mess of water, oil, high temperatures, and low temperatures, otherwise it will break down all of a sudden and it will be a big trouble!

1. Key points for material selection

The outer skin must be thick and solid. PVC is definitely not good. The second is polyurethane. It is better to have a little flame retardant properties to be more stable~

For internal conductors, use tinned copper or bare copper, and do not replace them with messy aluminum and iron. They may be easily broken if they are not conducting well;

2. Installation precautions

When you are walking, try not to make it turn around and turn, especially those with armor, which can easily be broken if it is too strong!

You must use a dedicated waterproof joint at the joints. Those with one turn and two and porous ones must choose a reliable brand of quality. Don’t buy a few dollars cheaper, otherwise you will not be able to cry even if you get water;

3. Different environment adaptation types

Environment Type	Recommended cable types	Core Feature Requirements
High temperature workshop (>80℃)	Silicone rubber insulated high temperature resistant cable	Continuous temperature resistance of 150℃ or above without degradation
Sea/wet areas	Double sheathed anti-salt spray cable	Anti-sea water corrosion and corrosion resistance
Outdoor burial scene	Steel belt armored polyethylene sheathed cable	Anti-rolling and anti-rodent bite

Many people will ask: "I have vibration and oily places, which wire should I choose? ~?" In fact, at this time, you have to choose the kind with a braided reinforcement layer, and use oil-resistant rubber on the outer skin - remember! Some people think that if the environment is poor, just buy thick roots, which is a big mistake! The thickness of the wire core is related to current. Strong environmental characteristics are the key to saving lives. Don’t put the cart before the horse - do you hear it?

When buying, you must check the third-party inspection report, such as UL certification and CE certification. Don’t believe it if the merchant is so arrogant. After installing it, check whether the outer skin is cracked or not, and whether the joints are loose. It is better to find small problems in advance than to suddenly break it!

Personally, I think Harsh would rather spend more money to buy expensive and reliable things than to change them every three days in order to avoid cheap things. If you delay things, you may also have safety problems. Everyone knows which one can get.
