XERO InsuPole Dielectric Testing: What It Means for Window Cleaners

What is the XERO InsuPole?

The XERO InsuPole is a fiberglass pole section designed to be used in pairs as the base section of your water-fed pole to help minimize the potential risk of accidental electrocution. When working near an electrical hazard, proper safety procedures should always be followed.

Was the XERO InsuPole tested?

Yes, XERO takes safety seriously and had SGS, a top-rated, third-party testing facility, perform their recommended testing on the InsuPole to see how it would perform. You can read the full test results from SGS for yourself here.

Did the XERO InsuPole pass testing?

Yes, the XERO InsuPole was tested up to 4,670 volts and passed. This testing was done in a laboratory under normal, dry conditions. There was no breakdown, arcing, or flashovers in any test.

What is a Dielectric Strength Test?

Dielectric Strength Tests determine how well something insulates against electric shock. The tests are meant to simulate real-world scenarios using standard voltage tests. In simple terms, it means making sure that electricity can't transfer through the section to your hands.

What standards were used for testing the XERO InsuPole?

Because there are no safety standards specifically for waterfed poles that may be operated in the vicinity of electrical lines, the closest standards were used for testing purposes:

• UL 61010-1: 2012 and UL 817, 13th Edition (2025) - These standards are commonly applied to hand-held electrical equipment. 
• UL 62368-1 - Referenced for more stringent Category III testing applied to industrial use or close to main power inputs.

Why was the InsuPole tested dry?

The lab determined this was the appropriate testing scenario because the material of the InsuPole doesn't absorb humidity. 

Since it passed, does this mean the InsuPole eliminates all electrical risk? 

No, it does not eliminate all risk. When working near live power lines, there is always a risk involved. The InsuPole is designed to minimize risk and is electrically resistant up to the tested 4,670 volts. Always follow proper electrical safety procedures. Never use water fed poles near energized power lines, even with the InsuPole.

Can I use my water fed pole near power lines with the InsuPole sections?

While the XERO InsuPole has been tested to withstand up to 4,670 volts under dry lab conditions, it is not rated for use near live electrical lines. Always stay at least 10 feet away from any power line. Assume all wires are live. This pole is designed to reduce risk, not eliminate it.

Can I view the test results myself?

Yes, we would love for you to check out the results for yourself. They are posted here.

The InsuPole is all I need to be safe, right?

No, the InsuPole adds a layer of protection, but it's not an all-encompassing solution. There are multiple steps to protecting yourself from potential electrical hazards. We recommend using dielectric overshoes and electrically insulated gloves as part of your PPE. There are also safety procedures to follow on the job site to ensure you're as safe as possible.
