Crimping Type Aluminium In-Line Connectors
Crimping Type Aluminium In-Line Connectors
CrimpingType Aluminium In-Line Connectors are electrical components designed to join two
aluminium conductors in a straight line (end-to-end) using a compression
(crimping) technique. These connectors are typically made from
high-conductivity aluminium and are used for splicing or extending aluminium
cables, particularly in power distribution systems, substations, and
overhead line networks.
These
connectors come in tube-like barrel shapes, with internal chamfering
or serrations for improved grip. They are installed using hydraulic or
mechanical crimping tools to ensure tight electrical and mechanical contact,
minimizing resistance and preventing overheating.
10 FAQs of Crimping Type Aluminium In-Line
Connectors
- What is the main use of an
aluminium in-line connector?
To connect or extend aluminium cables in-line while maintaining electrical
continuity and strength.
- How is it installed?
By inserting stripped cable ends into both sides and compressing using a
crimping tool.
- Are these connectors
suitable for copper cables?
No, they are specifically designed for aluminium conductors. Using with
copper can lead to galvanic corrosion.
- Do they need anti-oxidant
compounds?
Yes, applying oxide-inhibiting grease improves performance and lifespan.
- What are the standard sizes
available?
Ranges typically from 10 mm² to 1000 mm², depending on application.
- Can they be used in
underground installations?
Yes, but they must be properly insulated or used with heat shrink sleeves
for moisture protection.
- Are they reusable?
No, once crimped, they should not be reused to maintain connection
integrity.
- Do they require a specific
type of crimping die?
Yes, use dies recommended by the manufacturer that match the connector
size.
- Are these connectors tested
for short-circuit conditions?
High-quality ones are tested for thermal and dynamic short-circuit
performance per IEC/IS norms.
- What standards apply to these
connectors?
Common standards include IS 5561, IEC 61238-1, or equivalent
international specs.
