6 FAQs about [Branch joint]
What is a branch joint?
The branch jointing provides a reliable electrical connection, electrical insulation and mechanical protection. The connectors are either the compression or the mechanical type. The branch joints can be used for indoor, outdoor, submerged and underground cable jointing.
Do all branch joints come with connectors?
As standard all branch joints are supplied with connectors to suit the maximum branch cable size. Selection charts are for copper conductors. Where jointing aluminium conductors, sizes may differ. Please contact our technical department for assistance.
What is a Y type branch joint?
A typical Y type branch joint is as shown in figure 3 below. This is used to join low voltage, polymeric, non-shielded cables of between 1 and 5 cores. The branch jointing provides a reliable electrical connection, electrical insulation and mechanical protection. The connectors are either the compression or the mechanical type.
What is the difference between a straight through and a branch connector?
The simple joints such as the straight through connectors are used to connect two power cables at one point while the other more advanced branch connectors may be used to accommodate a cable branching off the main line or several cables coming into one joint to form one main cable.
What are the different types of cable joint sets?
The sets are available in various sizes as straight through i-Line joints and also as Y-Line and T-Line branch joints or PA parallel branch joints. They can be used for cable jointing underground, under water or in installation ducts, for example for connecting buildings to the mains supply.
What is a straight cable joint?
Straight joints can be used for indoor, outdoor, submerged and underground cable jointing. In the cast resin based cable joints, the polyurethane based casting resins provide mechanical protection, electrical insulation and moisture imperviousness to the joint. A typical Y type branch joint is as shown in figure 3 below.
