Moisture, humidity, reliability and electrical safety

Moisture, humidity is a great enemy for electrical power continuity and reliability. Excess moisture can cause: • Short Circuits: Moisture prepares a platform as conductive pathways, increasing the risk of short circuits and potential fire and a challenge for electrical safety. • Corrosion: maximum electrical components are susceptible to rust and oxidation, leading to malfunctions and equipment failure. This happens frequently in coastal area or where rainy season go longer. • Insulation Breakdown: lots of cause is for insulation breakdown. Humid conditions degrade the insulating properties of wires and cables, compromising electrical safety and performance. Automatic Dehumidifier & Temperature Controller are available to combat the negative effects of humidity on your electrical installations. Typical others like panel space heater, motor space heater, silica gel , canopy protection, sealing of switchgear rooms etc. are also available. • Material Compatibility and Degradation: availability of moisture in the air may like to cause problems for the efficient operation of electrical components because it prevents the materials from effectively connecting with one another. When moisture-sensitive adhesives or coatings are subjected to high levels of humidity.
Note: there is one scope i.e. earthing electrode where moisture content is helpful in decreasing specific gravity and finally reduce the earth resistance value.

Expandable barricade for electrical safety

Expandable barrier or barricade is used for temporary barricading. They are lightweight and easy to fold carry anywhere. It is frequently used by security department, police , Mall and many more. It is use for safety purpose in electrical construction or maintenance job. It is valuable in metal, plastic and fibre. Typical specification
