Mechanical properties.

Mechanical properties refer to the physical characteristics of a material that determine how it responds to applied forces or stress. In the context of insulation materials like DMD, mechanical properties are important because they affect how well the material can withstand mechanical stress, such as bending, stretching, or impact, without degrading or failing.

Here are some of the key mechanical properties of DMD:

Tensile strength: This is the maximum amount of stress that a material can withstand before breaking or deforming permanently. DMD has a high tensile strength, which means it can withstand a lot of stretching or pulling without breaking.

Flexibility: This is the ability of a material to bend or flex without cracking or breaking. DMD is relatively flexible, which makes it well-suited for applications that require a lot of bending, such as winding around transformer cores.

Tear resistance: This is the ability of a material to resist tearing when subjected to a sharp or sudden force. DMD has good tear resistance, which helps to prevent the material from tearing or puncturing when it is subjected to mechanical stress.

Elasticity: This is the ability of a material to return to its original shape after being deformed or stretched. DMD is relatively elastic, which means it can stretch and then return to its original shape without being damaged.

Overall, the mechanical properties of DMD make it a durable and long-lasting material for transformer insulation. Its combination of high tensile strength, flexibility, tear resistance, and elasticity allow it to withstand the mechanical stresses that transformers may experience during operation, while still providing reliable electrical insulation.

Various sizes for option:

Temperature Rating: DMD is capable of operating at temperatures up to 155°C (311°F) continuously, and up to 180°C (356°F) intermittently.

Dielectric Strength: DMD has a high dielectric strength, typically in the range of 8-12 kV per mil (0.001 inch) thickness. This means that it can withstand high voltage without breaking down or arcing.

Thickness: DMD is available in various thicknesses, typically ranging from 0.05 mm (0.002 inch) to 0.25 mm (0.01 inch), although other thicknesses may be available depending on the manufacturer.

Tensile Strength: DMD has a high tensile strength, typically in the range of 90-150 N/10mm (10-17 lbs/inch) in the machine direction and 60-100 N/10mm (7-11 lbs/inch) in the cross-machine direction.

Elongation: DMD typically has an elongation of 20-50% in the machine direction and 50-100% in the cross-machine direction. This means that it can stretch without breaking and return to its original shape.

Volume Resistivity: DMD has a high volume resistivity, typically in the range of 1-10 GΩ/cm, which means that it can resist the flow of electrical current.

Thermal Class: DMD is classified as a Class F insulation material, which means that it has a temperature index of at least 155°C (311°F) according to the IEC 60085 standard.
