fabricate high voltage wire and cable products‚ moulded electric components‚ and heat resistant seals and hose. PQD has also been used as part of the curative system for liquid butyl elastomers. These compounds are formulated as coatings‚ sealants and electrical encapsulants. The proper choice of PQD and a co-curative‚ such as lead dioxide or tertiary-butyl perbenzoate‚ will effect room temperature curing. PQD also functions as a curative for Ethylene Propylene Terpolymers (EPDM). Improved heat aging properties

Ward-Leonard Motor Generation System Introduction: A control system generally controls‚ regulates‚ and updates its output continuously based on present inputs‚ nature of the system‚ and the past outputs. In other words‚ there is a feedback mechanism that is inherent in the system‚ and is called a closed loop control system. For example‚ adding an emitter resistance to a common emitter amplifier‚ results in a negative feedback mechanism in the amplifier system – if the output current increases
