Choosing T300 carbon fibre is not a design decision. It is an engineering decision: extreme tensile strength, outstanding lightness, and electrical insulation in a single material.

CONDUCTIVITY[ 01 / PHYSICAL PROPERTIES OF T300 CARBON FIBRE ]
| Property | Value | What It Means for You |
|---|---|---|
| Density | 1.76 g/cm³ | 60% lighter than aluminium – overhead work without fatigue, hour after hour. |
| Tensile Strength | 3 530 MPa | Triple the tensile strength of steel – no bending, no give, even at full water pressure. |
| Elastic Modulus | 230 GPa | Superior bending stiffness – zero rebound, every ounce of force delivered straight to the brush head. |
| Electrical Conductivity | Far lower than aluminium | Far less conductive than aluminium – clear safety advantage for PV cleaning. Always keep safe distance from live parts. |

| Carbon Fibre T300 | 1.65 kg | Excellent | Very High | Much safer |
| Aluminium | 3.20 kg | Moderate | High | Hazardous (conductive) |
| Fiberglass | 2.90 kg | Poor (flexes under load) | Moderate | Safer (lower conduct.) |

Why Electrical Insulation Can Save Your Life
When wet-cleaning photovoltaic installations, conventional aluminium poles conduct electricity well – a serious risk if wiring is faulty or residual voltage is present. HARTFELS T300 carbon fibre conducts electricity far less than aluminium, significantly reducing this risk. Note: always keep a safe distance from live electrical parts.
