Dummy Load is a device used to simulate an electrical load during testing. In an RF System a dummy load is used to simulate an antenna. By using a dummy load instead of an actual antenna, the transceiver can be tested and configured without radiating radio waves.

Fixed attenuators are placed in signal paths to reduce power transmission and are set at a fixed attenuation by symmetrical resistive networks that follows a T, L or Pi configuration. Their configuration can either be in waveguide, in surface mount or coaxial, and depending on their application, they can either be directional or bidirectional.
Applications:
Attenuators are generally used in radio, communication and transmission line applications to weaken a stronger signal.

Application :-
The XLPE (Cross Link Poly Ethylene) Power Cables are used under ground as well as over head transmission of power
in power plants, industries, projects and all other electrical installations.
Features :-
Manufactured from bright annealed 99.97% pure bare copper & aluminum conductors. These cables are insulated
with XLPE compound. Taped/Extruded inner sheath. Round steel wire / flat galvanised steel grip armoured. The outer
sheaths can be PVC, HR PVC, FRLS or FR depending upon the application and requirement.
Technical Advantage of XLPE Insulation :-
Higher current rating, higher short circuit rating (approx 1.2 times that of PVC), thermosetting in nature, higher
insulation resistance (1000 times more than PVC cables), higher moisture resistance, better resistance to surge
currents, low dielectric losses, better resistance to chemicals and corrosion, longer service life. Comparatively higher

The function of a capacitor in a fan is to store electrostatic energy in an electric field and where possible, to supply this energy to the circuit. The role of a capacitor in a fan is to prevent a dangerous failure of the circuit, they allow the AC to move but block the flow of DC.
A condenser, also known as a capacitor, is used in a fan to help regulate the electrical current flowing through the mot.
The function of the condenser in a refrigeration system is to transfer heat from the refrigerant to another medium, such as air and/or water. By rejecting heat, the gaseous refrigerant condenses to liquid inside the condenser.
A condenser is an essential component within any HVAC system. Its purpose is to take in high-pressure refrigerant gas, emitted by the compressor, and convert it into liquid state. The refrigerant is cooled and then condenses at a virtually constant temperature and pressure.
A capacitor can help a fan motor to run at a higher speed by helping to regulate the current flowing through the motor. A capacitor is connected to the start winding in a Fan. In low power induction motor like fan it is left connected permanently, so as the capacitor ages speed of Fan reduces.
