Pros And Cons Of Polyurethane
High-grade jacket materials such as polyurethane (PUR) should be considered. PUR is resistant to harsh conditions such as oils, fire, abrasions and chemicals. Lower grade jacket materials, such as PVC, while less expensive cannot handle exposure to oils and chemicals and might degrade. PVC also becomes brittle and cracks at low temperatures. Material selection can be dependent on the material’s electrical, mechanical and environmental capabilities and the ease with which they can be attached to other materials through processes such as crimping, soldering and other processes. Connector materials are chosen such that they have minimal resistance, good electric conductivity, good machinability, and good stability over time and good hardness

Outer semiconductor: uniformly distribute the voltage on the surface of the insulation 5. Earth layer: made from copper, used to ground the cable, in case of short circuit it protect the cable by leaking the short circuit current into the ground, its thickness is about 25mm2 area 6. Filling: synthetic fibers used to make the cable circular and to fill the gap between the phases 7.

196 Words | 1 PagesOnce, the current rating and voltage rating are chosen, one needs to look at the data sheet of the connector to check whether it meets the given specifications. In the datasheet, one should look at the test procedure used to arrive at the specifications and check whether it meets the test standard. Not everyone uses the same testing criteria, so ensure you understand how these specifications were derived. It should also be confirmed that the contact will support the conductor size that has been chosen. A non-compatible conductor could cause overheating issues, leading to premature connector failure.

458 Words | 2 Pages[26]. The insulation resistance is measured using a mega ohm bridge or a mega ohm meter. An applied DC voltage is used to measure the insulation resistance of the connectors in kΩ, MΩ, or GΩ. If the connector is going to operate at special conditions, then the environmental requirements needs to be incorporated. The electrical insulation begins to age as soon as it is installed, this deterioration can affect the performance. It is used as quality control during production of the connector, preventive maintenance tasks and as a troubleshooting

588 Words | 3 PagesThey are created from industrial quality PVC which surrounds a patented acoustic absorbent foam. Hand stitching ensures that the panels are extremely strong and tests have shown that they are unlikely to deteriorate in extreme weather, making them especially suitable for the Canadian climate. The panels are robust at temperatures of -40 degrees and can withstand high force water pressure. They are also fire proof. As they are light and easy to roll up and transport, storage is not a problem.

1419 Words | 6 PagesThe type of board I will be using has a density of 100 kg/m but will retain the same thermal conductivity but using a different grade of polyurethane foam that has fire resistant properties. This type of insulation has a relatively high compressive and tensile strength but during its production it does give off quite large amounts of Co2 and does contain toxic materials that could prove to be harmful to the surrounding environment. Although more costly the insulation having a higher strength and fire resistance will ensure that less maintenance will have to occur and so could be less expensive long

Pros And Cons Of Adhesive Taping
1130 Words | 5 PagesCollegiate Athletes’ Perceptions of Adhesive Ankle Taping: A Qualitative Analysis by Erika Hunt and Sandra Short is a qualitative study to explore the athletes’ perceptions of adhesive ankle taping. Adhesive tape is a very popular treatment modality for athletic injuries because it can be used for retention of wound bandages, compression, stabilization, prevention of additional injuries, and protection of both acute injuries and recent injuries. Taping had been important of athletic training; the widespread belief in the effectiveness of ankle taping and the extremely high incidence of lateral ankle sprains among athletes’ results in the frequent use of adhesive taping on ankles in athletics today (Wilkerson, 2002, p. 280). Adhesive taping has been shown to decrease ankle sprain incidence by providing mechanical support and enhanced proprioception for foot-ankle complex (Cordova, Ingersoll, Palmieri, 2002, p. 281). The benefits of taping include ankle range of motion, strength, and neuromuscular control.
Pros And Cons Of Tanning Beds
399 Words | 2 PagesWith a simple phrase in any search engine, you will find countless articles showing definitive proof that tanning of any kind can be harmful. Artificial UV exposure such as tanning beds tend to be the argument of the decade waging war on those who care about other's health way too much vs people who want to appear darker for looks only to be seen 30 years later as a wrinkled, and leathery sun spot attraction. There tends to be little ground on the people in the middle. To those who maybe go tanning for a week straight for a wedding or a comparable large occasion, a tanning bed may not be life threatening. Many who carry a genotype of melanoma will not be aware due to it staying dormant; however, very little UV ray exposure could act as a catalyst to that same carrier.

What Are The Pros And Cons Of Roving Cloth
211 Words | 1 PagesAn advanced material that I believe would be helpful to the success of our filtration system is woven roving cloth. Woven roving cloth is a heavy and durable fabric that is intertwined by weaving the strips of cloth like a basket. The pros of using woven roving cloth are that it can filter the water through the small holes in between the weaves and it can keep particles out of the filtered water. Other pros of using woven roving cloth in our filtration system is that it is very durable therefore it will be able to withstand thick and sharp particles as well as the weight of water. The con to this material is that is does not have antimicrobial properties therefore does not trap bacteria from water.
