Product Description

Product Introduction:

The Black PE MJPT (Medium Voltage Polymeric Insulated Power Transmission) Plastic Pre-Insulated Sleeve is an advanced insulation solution designed for secure and efficient jointing of electrical cables in medium voltage power transmission systems. This pre-insulated sleeve provides a reliable and quick method for creating waterproof and gas-tight joints, ensuring the integrity and safety of the electrical connections.

Product Details:

  • Material: High-quality黑色聚乙烯 (Black Polyethylene) with excellent insulating properties.
  • Application: Suitable for medium voltage cable jointing in power distribution networks, both indoor and outdoor.
  • Compliance: Meets international standards for electrical insulation and safety.

Structural Features:

  1. Pre-Insulated Design: The sleeve comes pre-insulated, eliminating the need for additional insulation materials during the jointing process.
  2. Easy to Install: Can be easily installed using standard cable jointing tools, reducing the complexity of the installation.
  3. Waterproof and Gas-Tight: Provides a sealed connection that is resistant to moisture and chemical gases, protecting the joint from environmental factors.
  4. High-Temperature Resistance: Capable of withstanding high temperatures, ensuring reliable performance even in extreme conditions.

Installation Process:

  1. Cable Preparation: Clean and prepare the cable ends, removing any dirt or debris.
  2. Sleeve Placement: Position the pre-insulated sleeve over the cable joint area.
  3. Sealing the Joint: Use the appropriate tools to secure the sleeve in place and create a tight seal around the joint.
  4. Inspection: Conduct a thorough inspection to ensure the sleeve is properly installed and the joint is secure.

Applicable Environmental Conditions:

  1. Temperature Range: Designed to operate within a wide temperature range, typically from -50°C to +105°C.
  2. UV Resistance: The black polyethylene material offers excellent resistance to UV radiation, suitable for long-term outdoor use.
  3. Chemical Resistance: The sleeve is resistant to common chemicals, ensuring the joint’s integrity in various environmental conditions.
  4. Humidity Tolerance: Capable of withstanding high humidity levels, maintaining performance in damp environments.

Application Places

  1. Connection of Insulated Conductors: They are used to connect insulated conductors in distribution networks, facilitating the connection of residential and commercial buildings to the power grid, as well as for jointing conductors for distributive ABC cables with a voltage up to 1kV.
  2. Overhead Line Connections: The MJPT series pre-insulated sleeves are used to link or repair LV overhead connections, ensuring a secure and weather-resistant joint.
  3. Neutral Messenger in Aerial Bundled Cables: Specifically designed to connect the neutral messenger in aerial bundled cables, these sleeves provide full tension support and prevent water ingress with their elastomeric caps.
  4. Preventing Electrolytic Corrosion: The presence of a neutral contact grease within the tube improves the contact area and protects the aluminum against oxidation, which can lead to electrolytic corrosion.
  5. Crimping Operations: The installation of MJPT connectors is facilitated by standard tools with special dies, allowing for easy crimping operations once the terminal insulation is removed to the required length.
