Crimping Type Copper Long Palm / Two Hole Tubular Terminal Ends
Crimping Type Copper Long Palm / Two Hole Tubular
Terminal Ends
CrimpingType Copper Long Palm / Two Hole Tubular Terminal Ends are high-conductivity copper
terminals designed for terminating and connecting cables to electrical
equipment, busbars, or junction boxes. These lugs feature an extended palm for
improved electrical contact and two holes for secure double-bolt mounting, which
provides enhanced mechanical stability and vibration resistance. Manufactured
from high-purity, electrolytic-grade copper and typically tin-plated to prevent
oxidation, they are used in heavy-duty electrical systems such as substations,
switchgears, power distribution panels, transformers, and industrial machinery.
The crimping design ensures a strong, low-resistance bond between the cable and
the terminal, minimizing power losses and improving safety.
Top 10 Frequently Asked Questions (FAQs) of Crimping
Type Copper Long Palm / Two Hole Tubular Terminal Ends
- What is the purpose of a
two-hole copper terminal end?
It provides a secure, vibration-resistant connection by allowing the lug
to be bolted at two points.
- Why is the palm made longer
in long palm lugs?
The extended palm ensures better surface contact with busbars or
terminals, enhancing conductivity and reducing heat buildup.
- What type of cables are used
with these lugs?
These lugs are used with stranded copper cables or conductors in low- to
medium-voltage systems.
- What does “crimping type”
mean?
It means the cable is inserted into the tubular barrel and compressed
using a crimping tool for a secure, permanent connection.
- Are these terminals suitable
for outdoor use?
Yes, if properly insulated or used with heat shrink sleeves, and
especially when tin-plated to resist corrosion.
- What sizes are available?
Sizes range from 2.5 mm² to 1000 mm² and beyond, depending on the
application and current-carrying capacity.
- Why use two holes instead of
one?
Two holes offer better mechanical stability, reduce loosening under
vibration, and provide redundant contact points.
- Can these be used in
high-temperature environments?
Yes, copper terminals can typically withstand high temperatures (up to
105°C or higher depending on insulation used).
- Do they require special
crimping tools?
Yes, appropriate crimping dies and hydraulic or mechanical tools are
needed for proper compression.
- Are they compliant with
standards?
Quality versions are made per IS/BS/DIN/IEC or UL standards and undergo
rigorous quality control.
