Description

What is an Ailink Aluminium Connector?

An Ailink Aluminium Connector is a brand-specific MC4-compatible connector designed for connecting aluminium cables in solar panel arrays. The "MC4" (Multi-Contact, 4mm pin) style is the industry standard for solar applications due to its weatherproof, durable, and safe design for high DC voltages.

Their key differentiator is that they are engineered specifically for use with aluminium PV cables, not the more common copper ones.

Full Specification Overview

Here’s a breakdown of the typical specifications for an Ailink Aluminium MC4 Connector:

Feature	Specification & Description
Compatibility	MC4 Compatible. Can mate with other standard MC4 connectors from brands like Staubli, Amphenol, etc.
Contact Material	Electro-tin Plated Copper. Ensures excellent electrical conductivity and a reliable, low-resistance connection. The internal current path is still high-quality copper.
Cable Type	Designed for Aluminium Photovoltaic (PV) Cable. Features a unique sealing gland and ferrule specifically engineered to grip and seal against the larger diameter and different material properties of aluminium cable.
Cable Range	Typically accommodates 4mm² to 6mm² aluminium cable cross-sections. (Always check the specific product datasheet).
Housing Material	Engineering Plastic (Nylon PA66). Offers excellent resistance to UV radiation, weathering, and impact. It is also flame-retardant (UL94 V-0 rated).
Sealing	IP68 Rated. Provides a complete dust-tight and waterproof seal, even when submerged under water (typically at depths of 1m for 24 hours). This is critical for outdoor, long-term exposure.
Voltage Rating	Up to 1000V / 1500V DC. Standard for most solar string installations.
Current Rating	Typically 30-35 Amps (e.g., 30A for TUV certification, 35A for UL certification).
Temperature Range	-40°C to +90°C (-40°F to +194°F). Suitable for extreme environmental conditions.
Safety Certification	TUV, UL. Certified to international safety standards such as IEC 62852 (TUV) and UL 4128 (UL). This is a critical mark of quality and safety.
Contact Resistance	< 0.5 mΩ. Very low resistance to minimize power loss and heat generation.
Ingress Protection	IP68 (as mentioned above).
Flammability Rating	UL94 V-0 (Self-extinguishing).

Key Features and Benefits

Designed for Aluminium Cable:
- This is the most important feature. Standard MC4 connectors are made for copper. Aluminium cable is slightly larger in diameter for the same gauge and has different creep and cold-flow properties.
- Ailink connectors have a specialized ferrule and sealing gland that provides the correct mechanical crimp and long-term, gas-tight seal necessary for aluminium, preventing oxidation and connection failure.
Cost-Effective Solution:
- Using aluminium cable instead of copper can lead to significant material cost savings, especially in large utility-scale solar farms. Ailink connectors enable this transition without compromising connection safety or reliability.
High Reliability and Safety:
- With IP68 rating and UL94 V-0 flammability certification, these connectors are built to last for the 25+ year lifespan of a solar farm, resisting water, dust, UV degradation, and fire.
Easy Installation:
- They come as male and female pairs and are installed using standard MC4 crimping tools. Proper, manufacturer-recommended tools are essential for a reliable crimp.

Typical Applications

Utility-Scale Solar Farms: Where the cost savings of using aluminium cabling are most significant.
Commercial Rooftop Solar Arrays: For large commercial buildings.
Large Ground-Mount Solar Installations.
Any PV project specifically designed and engineered to use aluminium cabling.

Important Considerations

Not for Copper Cable: You should not use an aluminium-specific connector on a copper cable, and vice-versa. The incorrect fit will lead to a poor connection, high resistance, overheating, and a potential fire hazard.
Proper Tooling: Using the correct, calibrated crimping tool is non-negotiable for a safe and reliable connection. A poor crimp is a major failure point.
Certification Matters: Always ensure the connectors you purchase have the proper TUV or UL certifications to guarantee they meet international safety standards.
