Is your 33kV insulating rubber mat safe? 5 Tests that confirm its performance

 

A 33 kV insulating rubber mat is a barrier between you and potential electrical hazards. How can you be confident about your safety? Electrical accidents bring high stakes in the workplace. Thus, it is important to be sure about the reliability and integrity of your insulating mat.

Are you confident in the safety of your 33 kV rubber mat?

Are you sure that it passes these 5 important tests? 

There are different standards for insulating mats, such as ASTM D-178, IEC 61111:2009, and IS 15652:2006. Different standards are dedicated to different geographical locations. For example, Bahrain, Qatar, and the UAE usually use the IEC 61111:2009 standard. 

However, the IS 15652:2006 standard has the 33kV insulating rubber mat. The Bureau of Indian Standards has set this standard for insulating mats. The IS 15652:2006 has different classes, such as Class A (3.3 kV), Class B (11 kV), and Class C (33 kV). 

Make sure that your mat has passed the

5 tests that confirm the performance of the 33 kV insulating rubber mat:

1. Dielectric Strength Test:

Dielectric strength is an important feature in the 33 kV rubber mat specification list. It determines the maximum voltage it can withstand without breaking down. However, the maximum withstand voltage of a 33 kV insulating rubber mat is up to 33 kV. 

In this test, the manufacturers put the 33 kV rubber mat between testing electrodes. They start by applying voltage to the 33 kV rubber mat slowly. Voltage application continues for about a minute. Next, they monitor if the mat shows any signs of damage. 

2. Insulation Resistance Test: 

The purpose of this test is to measure the electrical resistance of the 33 kV insulating rubber mat. However, this test requires a megohmmeter or meger. This equipment helps apply suitable test voltages to the 33 kV rubber mat. 

The 33 kV mat manufacturers activate the tester and apply a suitable test voltage to the mat. In addition, they will measure the resistance of the mat.

3. High Voltage AC Leakage Test:

When there is a breakdown of insulation, there can be an unintended flow of current. However, a defective 33 kV insulating rubber mat can cause electrical leakage. High-voltage AC leakage ensures the resistance of the 33 kV rubber mat against electrical leakage. 

In this method, the manufacturer applies an AC voltage to the surface of the 33 kV rubber mat. After this, they monitor the electrical leakage. 

4. Flame Resistance Test: 

Overheating and manufacturing defects of high-voltage machines can cause fire outbreaks. Thus, it is necessary that the 33 kV insulating rubber mat is flame-retardant.

 

In this testing, the manufacturer subjects the insulating mat to a flame or heat source. Then they check if it melts or ignites under such conditions.

5. Shore Durometer Hardness Test: 

The hardness of a 33 kV rubber mat determines its durability and performance. If the hardness of the mat is less, it will be more prone to wearing and tearing. Meanwhile, too much hardness can make the mats brittle and crack. 

Manufacturers check the hardness of the 33 kV insulating rubber mat with this test. This test needs a durometer to measure the hardness. In this method, the durometer is made to press into the surface of the mat. However, they do this for approximately 15 seconds. The durometer scale shows a reading that indicates the insulating mat's hardness. 

To conclude, 

Major industries have critical high-voltage applications. Thus, workers operating such machines and circuits require optimum electrical safety. Reliable manufacturers offer quality-assured 33 kV rubber mats. Besides, they offer test certificates, high-end customer service, and a competitive 33 kV rubber mat price. The tests confirm the 33 kV rubber mat specification list and their performance. 

FAQ

Why do electrical mats have an anti-skid design?

Insulating mats may have a ribbed or dotted texture. Workers in the industries can have physical accidents due to slipping and falling. This anti-skid design increases the traction of the feet of the workers to the ground. Thus, reducing their chances of slipping and falling.

What is the standard 33kv rubber mat size?

The standard width of a 33 kV electrical mat is 1 meter. Besides, the standard length of the mat is approximately 10 meters. However, you may need different sizes for different industrial applications. You can custom-make your insulating mats according to your required size, thickness, design, and color.
