  ·     Why is XLPE cables are Cross-Linked? In XLPE insulation cables the rubber is vulcanized with addition of Small quantities of chemical additives. This will help to rearrange the molecular structure into a lattice this process will hinders the movement of molecules in the presence of heat. XLPE cable is insulated with hydronic tubing made of cross-linked polyethylene plastic (XLPE).  The XLPE insulation has a three-dimensional bond within the plastic. The insulation is a  thermoset, zero halogen insulation that provides flame retardant properties.  It is strong, durable, and temperature conducting.  This process of vulcanization is being carried out to increase the stability of the XLPE cables even at high temperatures. This process of Cross-linking polyethylene also improves current carrying capacity i.e. rating of XLPE in order to withstand higher short circuits and under normal load conditions. By this XLPE insulation, the problem...

  Fan Heater vs Radiant Heater vs Oil-Filled Heater: Which One Should You Buy? When the winter chill sets in, choosing the right room heater can make all the difference between cozy comfort and high electricity bills. With so many options on the market, it’s important to know how fan heaters, radiant heaters, and oil-filled heaters differ—and which one suits your needs best. Below, I’ll break this down from an engineer’s perspective but in a way that’s easy for everyone to follow. 1. Fan Heater (Blower Type Heater) How it works: A fan heater uses a heating element (usually a coil) and a small fan to blow warm air into the room. It’s like a hairdryer designed for a room. Pros: Quick Heating – Warms up small rooms in minutes. Affordable Price – Usually the cheapest option in the market. Portable – Compact and easy to carry. Cons: Noisy – The fan makes constant sound. Uneven Heating – The area near the heater becomes v...

  Introduction: Ceiling fans have become an indispensable part of our homes, providing comfort and style while keeping the air circulating. These seemingly simple appliances are the result of sophisticated engineering and careful design. In this article, we will delve into the construction of ceiling fans, exploring the components that come together to create a cool breeze in our living spaces. Motor Assembly: At the heart of every ceiling fan is its motor. This component is responsible for converting electrical energy into the rotational motion of the fan blades. Typically, ceiling fans use an electric motor that operates on alternating current (AC). The motor assembly includes coils, a rotor, and a series of capacitors to control different fan speeds. Blade Design: The design of the blades plays a crucial role in determining the fan's performance. The length, pitch, and shape of the blades affect the amount of air moved and the efficiency of the fan. Manufacturers often conduct...
