High split resistance due to fiber reinforced layer Hot melt adhesive designed specifically for pressurized closure

RSBA

Fiber-reinforced heat shrinkable closure for pressurized cable network maintenance

1.       General

   RSBA is the most advanced pressurized closure system available. It is based on a unique glass fiber reinforced heat shrinkable composite material. This new revolutionary material offers extra ordinary mechanical and environmental protection. Its reinforced material structure has an excellent split resistance during installation and superior mechanical toughness. The inner coating of hot melt adhesive guarantees a watertight and secure bonding to plastic and metal-sheathed cables. The white line inside of the trajectory and the temperature-sensitive paint on the sleeve can lead a good and right operation. The reinforced branch-off and straight closures have been developed to meet the increased demand in cable networks. The kit also contains a range of fully interchangeable air fittings which can be incorporated in the closure. These include a reversible valve, an air connector and a low profile blanking plug to reduce accidental damage.

2.       Features

---High split resistance due to fiber reinforced layer

---Limitation of split propagation in case of external damage to the sleeve

---Hot melt adhesive designed specifically for pressurized closure applications.

---Hot melt adhesive with wide temperature range

---Insensitive to sharp flame setting

---Range of closures to suit all cable sizes

---Few components, fast and easy installation

3.       Application

---RSBA closures are pressure-tight up to 70kPa pressurized telecom. cables networks.

---RSBA are suitable for use in manholes, for buried and aerial cables with polyethylene, lead and aluminium sheathing, up to 3600 pairs.

---RSBA closures are applicable both for straight as well as branch joints.
