Crimping Type Copper Four Hole Tubular Terminal Ends
Crimping Type Copper Four Hole Tubular Terminal
Ends
CrimpingType Copper Four Hole Tubular Terminal Ends are specialized electrical connectors used for
securely terminating and connecting copper conductors to bus bars, distribution
panels, or equipment terminals. These terminal ends are made from high-conductivityelectrolytic copper and are designed with a tubular barrel on one
end for crimping the conductor, and four bolt holes on the palm for firm
mechanical fixing. The four-hole design provides better contact, load
distribution, and mechanical stability—making them ideal for high-current and
critical electrical applications.
They are
commonly tin-plated to resist corrosion and oxidation, ensuring
long-term conductivity and reliability.
10 Frequently Asked Questions (FAQs) of Crimping
Type Copper Four Hole Tubular Terminal Ends
- What is a crimping type
copper four hole tubular terminal end?
It is a copper connector used to crimp onto cable conductors and fasten
securely to terminals or busbars with four bolts.
- Why are four holes used
instead of one or two?
Four holes provide enhanced mechanical stability, better current
distribution, and reduce heating at the connection point.
- What sizes are available for
these terminal ends?
They are available for various cable sizes, typically ranging from 10
sq.mm up to 1000 sq.mm or more.
- Are these terminal ends
tin-plated?
Yes, most types are tin-plated to prevent corrosion and improve
conductivity over time.
- Can they be used in outdoor
or corrosive environments?
Yes, the tin plating and durable copper base make them suitable for indoor
and outdoor electrical installations.
- How is the cable fixed
inside the terminal?
The conductor is inserted into the tubular barrel and crimped using a
hydraulic or mechanical crimping tool.
- Are these terminals
reusable?
No, once crimped, they should not be reused as the integrity of the
connection may be compromised.
- Do they support both solid
and stranded conductors?
They are primarily designed for stranded copper conductors, which
are commonly used in power cables.
- What standards do they
conform to?
Many are manufactured in compliance with standards like IS, DIN, BS, or
IEC, depending on region and application.
- What tools are needed to
install them?
A properly calibrated hydraulic crimping tool or mechanical
crimper matched to the cable size is required.
