Crimping Type Copper Tubular Terminal Ends (Long Barrel)
Crimping Type Copper Tubular Terminal Ends (Long
Barrel)
CrimpingType Copper Tubular Terminal Ends (Long Barrel) are high-conductivity copper
lugs designed to provide a secure and durable connection between cables and
electrical equipment. These terminals feature an extended barrel length,
allowing for better mechanical strength, enhanced electrical conductivity, and
improved crimping reliability. The long barrel ensures sufficient contact area
for crimping, reducing resistance and heat buildup, especially in high-load or
high-vibration environments. They are typically used in power distribution,
control panels, industrial machinery, automotive applications, and renewable
energy systems.
Top 10 FAQs about Crimping Type Copper Tubular
Terminal Ends (Long Barrel)
- What is the purpose of a
long barrel terminal end?
The longer barrel provides better mechanical strength and electrical
conductivity, especially during heavy-duty applications.
- Why are these terminals made
from copper?
Copper has excellent electrical conductivity, making it ideal for
efficient power transmission and minimal energy loss.
- What is the advantage of tin
plating on copper lugs?
Tin plating prevents oxidation and corrosion, enhancing the lug's lifespan
and maintaining conductivity.
- How do you crimp these
terminals?
They are crimped using compatible hydraulic or mechanical crimping tools
designed for long barrel lugs.
- Can these terminals be used
in high-temperature environments?
Yes, copper lugs are suitable for high-temperature applications, although
you must check the insulation and plating ratings.
- Are these terminals
reusable?
No, crimped terminals are designed for one-time use to ensure a secure and
safe connection.
- What cable types are
compatible with these terminals?
They are suitable for stranded or solid copper conductors, typically used
in LV and MV power cables.
- What standards do these
terminals follow?
They often comply with international standards such as IEC, DIN, and BS
for safety and performance.
- Can they be used in outdoor
installations?
Yes, especially when tin-plated, they resist environmental factors like
moisture and oxidation.
- How do I choose the correct
size of terminal end?
Match the terminal's barrel size with the conductor's cross-sectional area
and the stud size with the bolt diameter of the connection point.
