Keeping Delicate Electronics Safe in Extreme Environments

Have you ever wondered how satellites and other delicate equipment can possibly be made reliable, considering the kind of harsh environments that they live in? How can data transmission cable continue to work under extreme conditions? The answer is various technologies such as heat treatment, sleeving, and other ways of protecting delicate electronics. Read on to learn more about what we put our electronics through, and why we need to protect them.


It was back in 1945 that a science fiction writer by the name of Arthur C. Clarke became the first person to voice the realization that satellites could be used for communication purposes. He was absolutely right, and since the 1990s the entire human race has become almost completely dependent on satellites for global communication. When satellites fail, the consequences can be felt everywhere. In 1998, the failure of the Galaxy 4 satellite affected the use of pagers for nearly 80% of pager users across the planet. Today, a serious failure of multiple satellites could cripple global communications and defensive weapons systems.

Electronics aboard satellites are delicate, and yet they must be able to withstand the most extreme possible conditions. These can be everything from space dust to huge swings in temperature; and even the possibility of collision with meteors, other satellites, or space junk. Heat treatment, Safe T Cable, Techflex tight weave, and other protective inventions make it possible for satellite electronics to withstand the worst that space can throw at them.


At any moment on planet Earth there are an average of just over 9,700 airplanes in the air. Those planes are carrying close to 1.3 million human beings, and every one of those people hopes and plans to arrive safely at their destination. In order for them to do so, all the components and electronics on the airplane must work reliably.

Much like satellites, airplanes are subject to incredible changes in conditions within very short time frames. Air pressure changes drastically between ground level and the average commercial airline cruising height of 35,000 feet. Air pressure can change by 75% between take-off and cruising altitude, while outside temperatures change by about 60°F in a matter of minutes. Silicone sleeving and heat treatment help to keep the sensitive but vital electronics on an airplane functioning correctly no matter what happens.

Home and Work

Your own home or work site might not seem like an extreme environment in the same way that outer space is. But there is a lot that can happen even in these places, and electronics need to be able to deal with them. Every year there are 4,000 injuries and about 300 deaths in America due to electrical hazards. When it comes to workplace deaths, electrocution is the sixth most common cause.

Fortunately, if you live in a home that was built in the last 50 years, all cables and wires are probably coated in NM cable: a flexible type of non-metallic sleeve that has undergone heat treatment that protects you, your home, and the wires from overcurrents.

Overcurrents are eletrical hazards that occur when there is too much load on the electrical circuit. A short-circuit or an overload can be very dangerous, and this is why we use heat treatment on sleeving and install circuit breakers and fuses to minimize the chance of dangerous and deadly accidents.

When it comes to electronics, there is a lot that can go wrong. Fortunately, we have the technology to protect our cables and wires no matter where we have to send them: or what we need them to do.
