  • Epoxy Potting Compound

    Epoxy Potting Compound

    1.​‍​‌‍​‍‌ When dry, our electrical potting epoxy serves its main function as a protective barrier that at the same time insulates, shields against moisture, and prevents corrosion.
    2. Besides, our epoxy potting material is impact-resistant and protects against environmental stresses to significantly enhance cable joint reliability.
    3. Our cured epoxy resin potting mixture works at room temperature so it fits various uses like indoor, outdoor, underground, and underwater cable connection ​‍​‌‍​‍‌protection.

    High Voltage Stress Relief Mastic

    High Voltage Stress Relief Mastic

    1.​‍​‌‍​‍‌ The electric field at 11kV – 36kV cable joints and terminals is being uniformized by means of our electric wire adhesive tape, which effectively releases the stress concentration.
    2. The gaps between different parts of the installation are sealed tight with our adhesive mastic tape, which also acts as a good conductor to avoid partial discharge.
    3. Through our termination tapes, stress relaxation and insulation of cable accessories is obtained so that they work reliably and ​‍​‌‍​‍‌safely.

  • Stress Control Mastic

    Stress Control Mastic

    1.​‍​‌‍​‍‌ Through our electrical insulating adhesive a highly uniform distribution of electrical field can be achieved in 15kV cable joints and terminals so that stress concentration is well eliminated.
    2. A filler seal is used in our electrical stress control mastic for filling up the installation gaps tight, which minimizes the occurrence of partial discharge。
    3. Our electrical stress control mastic demonstrates very good compatibility with polymer cables and hence offers longlasting and trustworthy insulation ​‍​‌‍​‍‌protection.

  • Red Waterproof Sealing Mastic

    Red Waterproof Sealing Mastic

    1.​‍​‌‍​‍‌ Mastic tape used for cable termination can be operated from -40℃ to 90℃ with a high-performance thermoplastic material that remains flexible at low temperatures and not sticky at high temperatures.
    2. The red waterproof sealing tape has a self-fluxing solvent-free composition and offers high insulation resistance and good waterproof sealing after the process of curing.
    3. The red waterproof sealing tape is non-toxic and has anti-creeping characteristics a volume resistivity as 1.0×10¹⁵ Ω·cm can be achieved and by this the tracking is greatly ​‍​‌‍​‍‌prevented.

  • Polyurethane Resin Material

    Polyurethane Resin Material

    1. A Shore hardness of 90±5 provides mechanical protection as well as elasticity that make it easy to use in cable joints subject to temperature changes and mechanical ​‍​‌‍​‍‌stress.
    2. With a volume resistivity >1.0×10¹³ Ω·cm, dielectric strength >20 kV/mm, and water absorption <0.2%, it provides both electrical insulation and moisture protection.
    3. Because​‍​‌‍​‍‌ the resin is easy to flow and its gel time ranges from 15 to 25 minutes, it is quite simple to fill cable joints and intricate electrical structures with ​‍​‌‍​‍‌it.
