GRP Cable Trays Manufacturing Process

• A GRP Cable Tray is an industrial equipment which
  is used to carry the wires and heavy cables in
  the plant. It is named as GRP Cable Tray because
  these cable trays are made up of Glass Reinforced
  Plastic (GRP) material. It is a kind of composite
  substance which is obtained when fiberglass is
  reinforced with composite polymer material or
  plastic. Since the glass used is a fiberglass,
  therefore it is also known as Fiber Reinforced
  Plastic (FRP). Before the introduction of GRP
  cable trays, there were steel and aluminum cable
  trays in industries which were replaced due to
  several advantages of GRP cable trays over the
  typical steel and aluminum trays.
• A GRP Ladder is of two types- Ladder Type
  Chanel Type. A GRP cable tray is created by
  gathering diverse sorts of blends of reinforced
  cross sections, side runners, and rungs. The
  rungs are epoxy reinforced and secured to exhibit
  great strength against uniform burdens. While a
  GRP Channel type cable Tray is cuboid-pipe-shaped
  tray specially designed for lightweights.

• Here we will discuss about GRP cable trays
  manufacturing process. GRP cable trays are
  manufactured as per different industrial
  standards. The manufacturer should keep these
  standards in mind while manufacturing the cable
  trays. These standards predict the strength,
  electrical conductivity, thermal conductivity,
  and durability of the GRP cable trays. And the
  ladder type cable trays are supposed to have a
  high strength and low thermal conductivity.
• The other physical characteristics of GRP cable
  trays are listed below

1. High Strength to Weight Ratio

• The Ladder type trays are required to be light in
  weight and high in strength.
• And should bear maximum weight on them. In an
  industry, the weight of cables and wires is very
  high and therefore, it should have high strength.

2. Corrosion Resistant

• The Cable Trays are corrosion resistant and
  therefore are undoubtedly used in chemical
  industries. Here, the iron and aluminum generally
  corrode and have a short life.
• The GRP Cable trays are used in other industries
  also where there are chances of corrosion.

3.Low Thermal Conductivity

• GRP cable trays have very low thermal
  conductivity and can bear the heat of high
  temperatures.

4. Fire Retardant

• GRP cables are highly resistive to fire and can
  avoid fire accidents when any wire short
  circuited inside them.

5. High Durability

• Since the GRP cable tray has high strength and is
  highly resistive to corrosion, it can be used for
  many years and thus have high durability.

6. Excellent Electrical Insulation

• Being a fiberglass plastic material, it has a
  very good electrical insulation, which makes the
  chances of short-circuit or shock to the workers
  nearby to zero.

7. Easy Installation

• Since the GRP Cable trays are light in weight and
  are pre-drilled, it makes their installation in
  the plants very easy and comfortable.
• Thus GRP cable trays has found its usefulness in
  industries and plants to carry cables and wires
  and is now used widely in the industries.
