In today's construction and electrical industries, choosing the right cable is critical for safety, durability, and long-term cost efficiency. If you are looking for a cable that performs reliably in wet, corrosive, or underground environments, you have likely come across ACWU90.
So, what is ACWU90, and why is it trusted by engineers and contractors worldwide? This article will clearly explain what ACWU90 is, how it differs from other cables, its core benefits, and how to select the right type for your project - plus why Dongguan Greater Wire & Cable Co., Ltd. is your best choice for ACWU90 cable supply.
Definition of ACWU90: What is ACWU90?
ACWU90 stands for Armored Cable Wet Underground 90°C.
It is a high-performance armored cable specifically designed for wet, dry, and direct burial applications, meeting the strict CSA (Canadian Standards Association) requirements.
Construction of ACWU90 Cable:
- Conductor – Copper or aluminum for excellent conductivity.
- Insulation – Cross-linked polyethylene (XLPE) for high heat and chemical resistance.
- Armor Layer – Aluminum or steel interlocked armor for superior mechanical protection.
- Outer Jacket – Moisture-resistant and UV-resistant sheath for enhanced durability.
Key Features:
- Rated for continuous operation at 90°C.
- Suitable for wet or dry locations.
- Can be directly buried, eliminating the need for costly conduit systems.
This makes ACWU90 an ideal solution for residential, commercial, and industrial wiring projects.
ACWU90 vs. Other Cable Types
When selecting cables, ACWU90 is often compared to TECK90 cables. Below is a comparison to help you make the right choice:
| Feature | ACWU90 | TECK90 | |
|---|---|---|---|
| Application | Wet, underground, corrosive environments | Industrial, wet areas | |
| Conduit Requirement | No conduit needed – cost savings | Requires conduit or additional protection | |
| Temperature Rating | 90°C | 90°C | |
| Mechanical Protection | High – robust armored design | High | |
| Cost Efficiency | High – durable and cost-effective | Higher cost |
For projects where moisture resistance, corrosion protection, and direct burial are required, ACWU90 offers a superior balance of performance and cost savings.
