Satyam FRP Cable trays installation should be with the standard set by the National Electric Code and NEMA Publications VE-2. Satyam Cable trays supplies made to order, pre-fabricated cable ladder tray, and fittings as specified by the purchaser.

  1. Always observe common safety practices when assembling trays and fittings. Installations generally require some field cutting. Dust created during fabrication presents no serious health hazard, but skin irritation may be experienced by some workers.
  2. Operators of saws and drills should wear masks, long sleeve shirts, or coveralls.
  3. Fabrication with fiberglass is relatively easy and comparable to working with wood. Ordinary hand tools may be used in most cases.
  4. Avoid excessive pressure when sawing or drilling. Too much force can rapidly dull tools and also produce excessive heat which softens the bonding resin in the fiberglass resulting in a ragged edge rather than a clean-cut edge.
  5. Field cutting is simple and can be accomplished with a circular power saw with an abrasive cut-off wheel (masonry type) or hack saw (24 to 32 teeth per inch).
  6. Drill fiberglass as you would drill hardwood. Standard twist drills are more than adequate.
  7. Any surface that has been drilled, cut, sanded, or otherwise broken, must be sealed with a compatible resin.
  8. Carbide tipped saw blades and drill bits are recommended when cutting large quantities.
  9. Support the fiberglass material firmly during cutting operations to keep material from shifting which may cause chipping at the cut edge.
  10. Each tray section length should be equal to or greater than the support span.
  11. When possible, the splice should be located within a quarter span.
  12. Fittings should be supported as per NEMA FG-1.

Reference NEMA VE-2 (current issue) In as much as fiberglass cable tray is designed as a support for power or control cables, or both; it is not intended or designed to be a walkway for personnel. The user is urged to display appropriate warning cautioning against the use of this support as a walkway.
