Crimping Type Aluminium Tubular Terminal Ends
Crimping Type Aluminium Tubular Terminal Ends
CrimpingType Aluminium Tubular Terminal Ends are electrical connectors used for terminating
aluminium conductors to ensure a secure and reliable mechanical and electrical
connection. These terminal ends are designed with a tubular barrel that
accommodates the aluminium cable and a flat palm or pad that can be bolted to
terminals, busbars, or lugs. Crimping is done using a hydraulic or mechanical
crimping tool, creating a cold-welded connection that minimizes resistance and
enhances conductivity. These terminals are widely used in power distribution, switchgear,
control panels, and electrical substations, particularly where aluminium cables
are preferred for cost and weight advantages.
10 Frequently Asked Questions (FAQs) of Crimping
Type Aluminium Tubular Terminal Ends
- What is the purpose of
aluminium tubular terminal ends?
To connect aluminium conductors securely to electrical devices or busbars
by crimping.
- How are these terminals
installed?
By inserting the stripped cable into the barrel and crimping it using an
appropriate crimping tool.
- Why use aluminium instead of
copper terminal ends?
Aluminium is lighter and more cost-effective, making it suitable for
large-scale power distribution systems.
- Can aluminium terminals be
used with copper cables?
No, they are specifically designed for aluminium conductors; using them
with copper can cause galvanic corrosion.
- Are these terminals suitable
for outdoor use?
Yes, provided they are properly sealed and protected with anti-oxidation
compound and heat-shrink sleeves.
- Do these terminals require
pre-treatment before crimping?
Yes, the aluminium conductor should be cleaned and anti-oxidation grease
(like oxide inhibitor) applied.
- What standards do these
terminals conform to?
Most follow standards such as DIN 46235, IEC 61238-1, or IS 8309.
- What tools are used for
crimping?
Hydraulic or mechanical crimping tools with die sets matched to the
terminal size.
- What sizes are available for
these terminal ends?
They range from 16 mm² to over 1000 mm², depending on the application and
manufacturer.
- What is the difference
between crimping and soldering terminal ends?
Crimping provides a gas-tight, high-pressure mechanical connection;
soldering involves heating and is less reliable for high-power
applications.
