PREFAB BRANCH CABLES

Branch joints of NISHI-BRANCH MV are injection – molded with PVC compound. PVC cable sheath and injection – molded PVC bond together making them airtight and waterproof. An example of a branch joint is shown in Fig. 4. Up to four branch cables are equipped at one mold section. Electrical and physical properties of molded branch joints and head supports are authorized by Japan Electrical Testing Laboratory Inc. according to JCS ( Japan Cable Makers’ Standard ) 376 : Cable with Branch Lines.

Economy
Total expenses of construction work, including personnel & material expenses, are considerably decreased because of saved manpower at the site.

Cutdown of construction period
Most of the site work is carried out at the factory of NND. It saves time and labor at the site.

High quality
Branch and head-support work that affect the electrical and physical  properties of the system are carried out at the factory if NND under severe quality control and well-arrange working environment.

Simple management at the site
NISHI-BRANCH MV is wound around drum and arranged for easy installation at the site. Therefore, the management work at the site such as arrangement of installation schedule, procurement and storage of necessary materials, etc. is reduced.

Decrease in shaft space
The shaft is used only for pulling up NISHI-BRANCH MV, therefore the required shaft space is reduced. This leads to effective use of land. If fire-proof measures at floor penetration sections are required, less space means less amount of fire-proof materials

Airtight and waterproof
The branch joints and the top end of each main cable are so airtight and waterproof that NISHI-BRANCH MV is applicable to a humid or wet area.

Phase identification
Both the main cables and branch cables are colour coded for easy phase discrimination by request.

No need of trunking
NISHI-BRANCH MV can be fixed to the wall with cleats or brackets. Costly trunking is not necessary.
