Branch off uncut cables

Whenever cables need to be branched off, the interruption of the cable is a potential weak point. The insulation is removed, the conductor is cut and a branching option is installed.

Moisture can then penetrate these clamping points and cause corrosion. In addition, mechanical forces can sever this connection and loose wires can lead to short circuits. Irrespective of this, such connections are a major safety risk, especially in the event of fire.

swibox, which has been active in tunnel construction for decades, has recognised this safety requirement and developed a product with which cables can be branched off without being cut: The UCB box.

UCB-Box in detail

The UCB box consists of a sturdy metal enclosure,
manufactured in the typical swibox quality.

UCB-Box enclosure technology

  • Sheet steel, powder-coated in RAL colour of your choice
  • Stainless steel 1.4571 e.g. for road tunnels
  • Stainless steel 1.4016, powder-coated in RAL colour of your choice
    (for tunnels and systems with increased corrosion protection)
  • Protection class: IP66
  • Impact resistance: IK10
  • Easy-to-install cover holder, for easy overhead installation.
  • The cover is fitted with a cover captive lock.
  • Cover screws with captive lock
  • Conical housing halves. This allows better access for mounting the terminals inside.
  • External fixing lug
  • Fastening is adjustable
  • At 360 x 100 mm, the smooth flange surface is large enough to allow junction boxes, electrical connectors etc. to be easily flange-mounted.

Clamps

The clamps in the UCB-Box consist of so-called piercing clamps.

Branch and feed-through terminal blocks with user-friendly piercing technology.

Advantages

  • Quick and easy installation of the clamp
  • The tear-off screw always ensures the correct torque
  • This ensures secure contacting
  • The conductor remains uncut
  • No time-consuming stripping

Cross-sections

  • 10 – 50 mm² through, 1.5 – 10 mm² branch
  • 16 – 120 mm² through, 6 – 50 qmm² branch
  • Copper and aluminium cables can be contacted

Cable gland

  • One seal for many cross-sections
  • Sealing range 10 mm to 52 mm diameter
  • Individually removable rubber discs

Branching with UCB-Box

Conventional branching

  • Large housing so that the bending radius of the wires is maintained
  • Time-consuming wiring in the housing
  • Limited space for connecting the wires
  • Cable protrusion to be able to adapt wires
  • Excess cable must be disposed of
  • Screw terminals must be maintained regularly
  • Screw terminals must be tightened with torque

Branch-off with UCB-Box

  • The straight-through cable is fed straight through
  • Quick and easy contacting
  • Only the cable sheath needs to be removed
  • Piercing terminals are maintenance-free
  • Only one screw for through and branch contacting
  • No torque spanner required as the contact is made with a tear-off screw
  • Simple branching of existing cables

Functional integrity: UCB-Box with flanged enclosure

  • UCB-Box P90 feed-through enclosure 50 mm²
  • E90 cable terminal housing (feed-through enclosure) made of stainless steel 1.4016, powder-coated
  • E90 cable terminal housing in accordance with EN 61439, fitted with temperature-resistant piercing terminals
  • Tested in accordance with DIN 4102 and EN 1363 over a period of 90 minutes
  • Flanged empty enclosure including C-rail and connection material, can be fitted as required
  • The combination fulfils the requirements of EN 61439 and electrical functional integrity in continuity.

Area of application

  • Road tunnels
  • Railway tunnels
  • Industrial construction
  • Building construction
  • Branching of existing lines

Feed-through enclosure Functional integrity

  • Protection class: IP66
  • Impact resistance: IK10
  • Housing dimensions: H 395 x W 185 x D 150 mm
  • Ambient temperature: – 25°C + 50°C
  • Housing: Halogen-free
  • Colour code: RAL 2003
  • Housing material: Powder-coated steel
    Alternative: Stainless steel, powder-coated
  • Sealing range: Ø 10 mm to Ø 52 mm
  • Rated voltage: 400V AC
  • Insulation base Vrms, 50Hz: 1kV
  • Rated current: 16A
  • Piercing terminals Clamping range in feed-through 16 – 50 mm²
    Clamping range in branch 1.5 – 10 mm²
  • Steatite spacer
  • External fixing lug
  • Cover holder
  • Cover loss protection

Flanged enclosure

  • Protection class: IP66
  • Impact resistance: IK10
  • Dimensions of enclosure: H 300 x W 150 x D 120 mm
  • Ambient temperature: – 25°C + 50°C
  • Enclosure: Halogen-free
  • Colour code: RAL 7035
  • Enclosure material: Sheet steel, powder-coated, C4
  • Rated voltage: 400V AC
  • Insulation base Vrms, 50Hz: 1kV
  • Rated current: 16A
  • Function maintenance cores in the branch
  • Equipped with 16A thermal switches

The thermal switches consist of high-temperature resistant enclosures. The bimetal switch interrupts the power connection once when 180°C is reached. The continuity of the function is therefore maintained and the branch cannot generate a short circuit.
The flanged enclosure can be freely equipped behind the thermal switch.
