WKL Aluminum (Aluminium) Compression Terminal Lugs — Fire-Resistant — 50 / 95 / 150 / 240 mm²
WKL series aluminum terminal lugs are compression-type splice/termination connectors manufactured from high-quality aluminum (aluminium) alloys for efficient current transfer and reduced mass. Designed for reliability across temperature fluctuations and corrosive environments, they are suitable for power distribution, renewable energy, marine, automotive, aerospace, and industrial systems. Materials contain no high-concern chemicals. Factory certifications include ISO 9001; product compliance includes CE and RoHS.
Functional Characteristics
- Type: Compression terminal lug / splice for aluminum conductors.
- Material: Conductive aluminum alloy with low resistivity and good corrosion performance.
- Fire resistance: Non-organic metal construction supports fire-resistant use cases (verify flame/exposure rating per installation code).
- Thermal behavior: Stable contact under thermal cycling when crimped with specified dies.
- Surface: Bare aluminum (apply oxide-inhibiting compound on conductor as required by site spec).
- Applications: Switchgear, panelboards, meter/service terminations, PV combiner/inverters, industrial power drops.
- Chemical profile: High-concern chemicals: None.

Selection Matrix — Conductor Matching
Select the WKL size to match the conductor cross-section; use the crimp die that corresponds to the same mm² class.
| Model | Conductor Size (mm²) | Approx. AWG | Approx. MCM | Typical Use | Notes (Fill Per SKU) |
|---|---|---|---|---|---|
| WKL 50 | 50 | ~1/0 AWG | ~100 MCM | Feeders, branch circuits | Populate: barrel I.D./L, stud size, pin/palm geometry |
| WKL 95 | 95 | ~3/0–4/0 AWG | ~190 MCM | Service entrance, PV DC | Populate: recommended torque/creep limits |
| WKL 150 | 150 | — (MCM class) | ~300 MCM | High-current feeders | Populate: two-stage compression sequence |
| WKL 240 | 240 | — (MCM class) | ~475–500 MCM | Utility/industrial mains | Populate: required stud size, palm width |
Tip: Publishing exact barrel I.D., barrel length, palm/stud dimensions, and overall length for each WKL model captures long-tail searches (e.g., “WKL 150 aluminum lug 12 mm I.D. 10 mm stud”).
Installation & Handling
- Conductor prep (Al): Strip to length; remove oxide layer; apply aluminum-approved oxide-inhibiting compound if required.
- Crimping: Use calibrated hex or dieless dies matching the mm² size; follow die sequence for larger lugs.
- Inspection: Verify full barrel compression and conductor insertion; perform pull test per site procedure.
- Interface caution: For aluminum-to-copper terminations, use approved bi-metal pads/washers or a bimetallic lug as specified by code/equipment maker.
- Environmental: Seal as required for outdoor or corrosive locations; re-torque hardware after thermal cycling if mandated by spec.
Applications
- Power distribution panels and switchgear
- Renewable energy (PV combiner/inverter DC links)
- Industrial machinery and MCCs
- Marine and transportation electrical systems
- Aerospace/defense support equipment (weight-sensitive harnessing)
Compliance & Chemical Disclosure
- RoHS / CE: Compliant per supplier declaration.
- ISO 9001: Factory quality-management certification.
- High-concern chemicals: None reported.
Technical FAQ
Are these lugs suitable for copper busbars?
Use per equipment and code: for Al-to-Cu interfaces, employ approved bi-metal interfaces or specify a bimetallic lug to mitigate galvanic effects.
What die should I use for WKL 95 or larger?
Match the die to the mm² size stamped on the lug; large sections may specify a multi-indent/hex sequence—refer to the product datasheet/tool chart.
Do these terminals have a defined flame rating?
Listed as fire-resistant by function; consult the datasheet for any specific flame class or exposure duration applicable to your jurisdiction.
