SUBMARINE® Branch Series
Cast resin joints
for Y branch connections
The SUBMARINE® Branch Series kits allow 0.6/1 kV single and multicore cable connections with up to ve
conductors. Kits include:
▪ two transparent half-shells with snap-shut closure and a 30° branch connector, so that
the connection is visible before the resin is poured
▪ two-component solid state polyurethane resin, already in the correct mixing ratio
▪ Direct Injection pouring system (DIPS) allows to inject the pre-mixed resin
inside the joint, without contact with the external environment. No leakage
and no personal contact, ensuring maximum safety for the operator and
the environment
▪ cores separator and in some versions an insulated ve-pole terminal block
– which enables connection without interrupting the main cable – and Allen key.
Technical specifications
▪ Compliant with the standard for 0.6/1 kV low
voltage joints (CEI EN 50393)
▪ Protection degree: equivalent to IPX8
(CEI EN 60529) tested in water at a depth of one
metre (CEI EN 50393 par. 8.6.3)
▪ Operating temperature: -20 to 90 °C
▪ Double insulation (in the version with terminal
block)
▪ Final solid state polyurethane resin (green colour)
▪ Shelf life: 3 years
84
