Splitting closures MVR-RWD

The MVR splitting closures are designed to organize a perpendicular branch (tapping) from the trunk cable line on symmetrical high-frequency cables operated under excessive air pressure and laid in the road beds of railways or cable structures.

The closure set includes:

  1. Polyethylene body;
  2. Shield connectors;
  3. Shield wire;
  4. Shield bus;
  5. LDPE sleeves;
  6. Tape 107-02К;
  7. Copper mesh;
  8. Mastic tape 2900R;
  9. Spring rings;
  10. Clamps;
  11. Sealing tape;
  12. PVC tape;
  13. ArmorCast reinforcing tape.

Technical performance

The closures consist of a T-shaped polyethylene body consisting of additional materials.

The closures comply with the requirements of the “Rules for laying cables in the road bed of railways. TsSh/52».

Design features

  • The body of the closure and the used sealing materials are resistant to aggressive media, possible all-weather conditions and ultraviolet, which makes the closure reliable and durable;
  • The closure is not subject to destruction by stray currents of alternating current electric traction;
  • The closure provides galvanic contact of the sheath with the cable armor;
  • For sealing the closure, no fire is required;
  • The closure can be installed with residual positive pressure in the cable line, which greatly simplifies and accelerates its installation.
