Characteristic advantages

insulation performance

Epoxy insulation pipes are based on epoxy resin and reinforced with alkali free glass fiber cloth to form a dense structure. They have high electrical resistivity (>10 ¹Ω· m) and low dielectric loss, and can withstand high voltages (such as 30kV withstand voltage testing) without being easily broken down. They are key insulation components of high-voltage equipment (such as transformers and switchgear).

Excellent mechanical strength

After glass fiber reinforcement, the bending strength is ≥ 300MPa, the shear strength is ≥ 25MPa, it can withstand mechanical pressure and impact, is not easily deformed or damaged, and is suitable for heavy-duty scenarios (such as rail transit contact network support devices).

Heat, moisture, and chemical stability

The heat resistance level covers Class B (130 ℃) to Class H (180 ℃), with a long-term use temperature of over 130 ° C and a short-term heat resistance of over 200 ° C. It is resistant to acid, alkali, oil, and organic solvents, suitable for humid environments (such as transformer oil) and harsh working conditions.

Broadband applicability

It can be applied from high-frequency circuits to low-frequency power transmission, such as insulation isolation of electronic components, cable support for high-frequency communication base stations, etc.

Usage precautions

Selection matching

Select the model based on voltage level and heat resistance requirements (such as G11 epoxy tube resistant to SF6 gas corrosion, suitable for high-voltage circuit breakers). For example, FR4 epoxy tubing is commonly used for voltages below 35 kV, and customized thickening design is required for ultra-high voltage scenarios.

Installation environment control

The construction environment should be dry and dust-free, avoiding moisture or chemical corrosion (such as strong acids and alkalis), and preventing long-term direct exposure to ultraviolet radiation (which may reduce insulation performance). Clean the contact surface before installation to ensure that there are no impurities affecting the insulation effect.

Operating Specifications

The installation process should be carried out in one go to avoid structural damage caused by repeated disassembly; When fixing, the force should be moderate to prevent stress deformation caused by excessive looseness, detachment, or tightness.

regular maintenance

Regularly inspect the appearance (cracks, deformations), clean the surface (wipe with a soft cloth), and evaluate performance through insulation resistance testing and dielectric strength testing. Establish maintenance logs, record detection data, and promptly identify potential issues.
