Which metal is used in safety fuse?
The commonly used fuse wire is made of an alloy of tin and lead.
Which is the material used for making fuse wire of safety fuse?
An electrical fuse is a circuit protection device that protects electrical circuits by breaking the connection in the event of a short circuit. Because of its high resistance and low melting, fuse wire is made of Sn (tin) and Pb (lead) alloy.
Which wire is used in safety fuse?
From the given options, alloy of tin and nickel possesses the least melting point. This material is extensively used for the production of fuse wires. Hence the correct option is D.
What is safety fuse made of?
A safety fuse consists of a black powder core in a textile tube, covered with asphaltum or other waterproofing agent, and having an outer wrapper of tough textile or plastic. They are made in a standard diameter designed to be crimped into blasting caps.
Which metal is used to make wire?
wire, thread or slender rod, usually very flexible and circular in cross section, made from various metals and alloys, including iron, steel, brass, bronze, copper, aluminum, zinc, gold, silver, and platinum. The processes used are all fundamentally the same.
Which wire is used for safety purpose?
Safety wire is available in a variety of gauges and materials, depending on the application. In aircraft and racing applications, stainless steel wire is used, such as in 0.032 in (0.81 mm) diameter.
Which material is used for making fuse?
The material used for making fuse element has a low melting point such as tin, lead, or zinc. A low melting point is, however, available with a high specific resistance metal shown in the table below. The material mainly used for fuse element are tin, lead, silver, copper, zinc, aluminum, and an alloy of lead and tin.
Which material is best for fuse wire?
Thus, a fuse material must be made up of a material which has high resistance and low melting point. The fuse wire is generally made up of high resistance and low melting material preferably Sn (tin) and Pb (lead) alloy.
What is fuse wire?
Answer: A fuse wire is a safety wire connected in series with the live wire, in case of any large current supply or malfunctioning in the electric connections it melts and breaks the electric circuit. Characteristics: High resistivity. Low melting point.
What is safety fuse in blasting?
The blasting safety fuse, employed to fire an explosive from a distance or after a delay, is a hollow cord filled with a mixture resembling black powder and designed to propagate burning at a slow and steady rate. The far end of the fuse is usually embedded in the explosive charge.
Why is Copper called metal?
Answer: Copper is called key metal because it’s a mineral and an element essential to our everyday lives. it’s even a major industrial metal for its high ductility malleability thermal and electrical conductivity and resistance to corrosion.
What is electrical wire made of?
While the terms wire and cable are often used interchangeably, a wire is one electrical conductor and cable is multiple conductors, or a group of wires, encased in sheathing. Electric wires are typically made of aluminum or copper. They are either bare or insulated and typically covered in a thin layer of PVC.
