SHUNTS
Introduction:
Permanent Magnets Limited is an ISO:
9001 company having world 
class manufacturing facilities for Permanent
magnets, Magnetic assemblies, Hi permeability components made from Fe-Ni soft
magnetic alloys & Electron Beam
Welded Manganin Shunts, Manganin Shunt & Assemblies.
SHUNT is precision element for the
energy meter which works in all kinds of electrical meter as power measurer.
·
The Manganin Shunt resistor is use as
a key part of the measuring device inside the electronic ammeter.
·
The EBW type shunt is able to achieve
a more precise parameter due to less heat transfer and reliable structure.
It also helps to saving the cost of production process and material.
PML’s vast experience of over 45 years
of dealing with magnetic measurements and properties makes PML the first choice
for customers.
PML
Shunt Assembly Properties:
·
Material: Manganin, an alloy of Cu
(84-87%), Manganese (9-12%) and Ni (2-4%)
·
Welding Type: Electronic Beam welding.
·
We can design EB welded Shunts or full
Manganin depending on Customers Specification and requirements.

Customized designs are available against
customers' drawings/samples.
Process Flow for SHUNTS:
•
Selection of copper & manganin as
per the customer drawing.
•
EB Welding
•
Inspection and testing
•
Punching
•
Assembly with terminals if required by
customer
•
Packing and dispatch
Tooling and Stamping:
The process is done at our expert
vendor specially developed for the application.
PML can manufacture any type of
customized design suited to the application which includes a complete manganin
shunt & assembly, EB welded shunt & assembly, Copper –Manganin welded
shunt assembly etc along with brass terminals.
Inspection & Testing:
·
The inspection is done as per the 0.65
% AQL sampling plan.
·
Testing of electrical resistance is carried
out on high precision micro ohm meter.
The
lowest resolution of the meter is 0.1 µΩ
