R & D
We give immense stress on Research & Development at various levels of dealing and testing. Continuous improvement in the quality of existing products, services and development of new products is a policy matter at our works.
We develop cables to suit the stress & strain of installation conditions at various industries.
-----------------------------------------------------------------------------------------------------------
Product Packaging
We are capable of meeting the most strict delivery schedules. Meeting the deadline is always the top priority as any delay in the delivery of cable can contribute to overall project delay and cost overrun.
Cable is supplied in wooden reels, corrugated boxes and coils. Cable ends are sealed with BOPP self adhesive tape and non-hygroscopic sealing caps to protect the cable ends from moisture.
