In Saudi Arabia, you can reasonably expect summer temperatures to exceed 45°C (113°F), which can produce thermally induced impacts on electrically powered components that can influence performance and permanence and, in some cases, result in catastrophic system failures. As an example, the extreme thermal stress change in an electrical component can deteriorate, disrupt, and ultimately destroy the device. The sustainability and reliability of electrical appliances, from residential air-conditioning units to industrial equipment and temporary and permanent infrastructures, will be increasingly interrogated as summer heat stress increases thermal-induced stresses on components even higher than existing thermal impacts. Not knowing how extreme heat will impact the operational performance of electrical components is essential to ensure they remain operable without causing the first responder unwanted interference or possible maintenance costs, and one of the singularly most important aspects in the residential or commercial sectors is creating a secure way of living.
Electrical components ultimately make up all electrical and electronic systems and are utilized to control, regulate, and distribute electrical energy. With regards to “electrical components,” we are describing above-average resistors, capacitors, transistors, and everything in between circuit breakers, transformers, switches, relays, wiring systems, etc. As described above, regions like Saudi Arabia face the ever-present risk of extreme heat, putting thermal added stress on electrical component performance and dependability. For example, in the extremes of heat, a circuit breaker could frequently trip much quicker than anticipated.
Capacitors and transformers will operate slower and deteriorate in high-heat environments. Electrical insulation on wiring can melt, harden, and rupture or cause the wiring to be vulnerable to short circuits or create a serious threat to electrical fires. It is also useful to think about what heat will do to how photovoltaic inverters and control panels perform in photovoltaic systems for solar energy when thermal extremes occur. Solar is very popular in the Kingdom. When considering all these issues, it is fundamental to consider how these semi-loose components would respond to extreme heat to create heat-resistant options.
Capacitor Degradation
Capacitors, particularly electrolytic types, are especially vulnerable to temperature changes. At extreme temperatures, the electrodes experience electrolyte evaporation at an accelerated pace, drying out the capacitor and reducing capacitance to a point where the circuit can no longer function. In HVAC applications, power supplies, and motor start-up circuits—which are common practice throughout Saudi Arabia—when capacitors fail in the circuit, it causes numerous circuit breaks, elevates maintenance costs, and decreases energy efficiency.
Resistor Drift and Overheating
Resistors are passive devices designed primarily to limit current and dissipate that energy as heat. The internal resistance value can drift from the original nominal values due to high ambient temperature. This will thereafter lead to undoubtedly poor accuracy and performance, especially in specific applications such as instrumentation and control. Resistors are also susceptible to thermal fatigue in hot environments or hot cycles, as thermal cycling and extreme temperatures may crack the resistive layer and lead to an open circuit or permanent damage.
Transformer Efficiency and Insulation Failure
Transformers regulate the voltage levels of power distribution to workloads, but extreme temperatures very importantly affect them. Excessive heat deteriorates the insulation on the windings, aging the insulation and quickly reducing its dielectric strength, which in turn leads to short circuits. In Saudi Arabia’s harsh induced climate, such heat will only hasten the aging process and reduce the operational life of a transformer. Just like the deterioration of capacitor performance due to increased heat generation because of excessively high temperatures, transformers can behave inefficiently as operational limitations are exceeded, which reduces the reliability of the overall power supply, e.g., in an industrial or commercial setting.
Circuit Breakers and Relay Failure
Protective devices such as circuit breakers and relays are designed to operate within specified thermal limits. However, when exposed to hot ambient temperatures, these devices can trip unnecessarily or fail to trip without warning due to deformed contacts and weakened springs. Therefore, the protection of electrical systems is compromised, resulting in a potential overload situation and possible fire hazard. In Saudi, the most demand on electrical infrastructure occurs at hotter times of the year when the thermal limits of many devices are being challenged; the correct rating of breakers and thermal relays, in particular, is vital for the integrity of the whole electrical system.
Semiconductor and IC Overheating
Semiconductor devices, which comprise transistors and integrated circuits (ICs), are incredibly sensitive to temperature. High temperatures facilitate the generation of unwanted leakage currents, degrade switching speeds, and can even lead to thermal runaway, pronounced and excessive self-heating, causing the component to fail. In Saudi and other similar environments, where buildings and infrastructure are incorporating more smart systems and automated controls, the assurance of correct cooling and ventilation of electronic circuits is paramount to achieving stability and reliability of your systems.
Wire and Insulation Failure
The insulation on wiring is often made from materials such as PVC and rubber, which, over time, lose their integrity when subject to continuous extremes of heat. This is typically surface melting, hardening, or cracking, which, as you can guess, greatly increases the risk of short circuits, arcing, and fire. The severe desert heat is taxing on surface-exposed cables in homes and industries. In this case, it is always better to have heat-tolerant insulation and a conduit system that will protect wiring.
Reduced Lifespan and Maintenance Effort
All electrical components have a rated operating life typically based on average temperature conditions. As noted earlier, Saudi Arabia’s extended exposure to extreme heat conditions accelerates electrical component wear, consequently increasing failure rates and off-time maintenance effort. Equipment with limited or reduced useful life increases maintenance effort and expenses. Poor component selection may also result in excessive system failure—meaning the downtime that happens in the summer during peak demand. It is critical to design systems and specify component ratings that support high temperatures and other conservative thermal management practices.
Protection Against Extreme Heat for Electrical Components
In Saudi Arabia, effective cooling protection methods must protect electrical components from extreme heat. One of the more important strategies and proactive measures is ensuring proper ventilation in electrical enclosures and control panels. Heat sinks, cooling fans, and air conditioning in the electrical rooms can also be utilized to keep operating temperatures at safe levels. The use of thermal insulation materials and the placement of heat shields will prevent sensitive components from being damaged by direct sunlight and from absorbing ambient heat.
Selecting components rated for high-temperature use, such as heat-resistant wiring materials, UV-protected insulation, and industrial-grade circuit breakers, greatly improves equipment durability. Maintenance and inspection will be separate but equally important in preventing early signs of heat and its associated wear pattern damage. Technicians will routinely check surface temperature indicators of discolored and/or melted insulating materials, loose connections, and components clearly demonstrating thermal fatigue. The use of thermal pastes and protective coatings can protect semiconductor and/or power device heat dissipation effectiveness. Finally, consider adopting smart monitoring system hardware types with semiconductor and/or electronic temperature.
