Sumip Ladder & Perforated type Cable
Tray provides reliable cable support in corrosive
application. Both Polyester & Vinyl ester resin
systems are available & all components incorporating
U.V. Stabilizer & a surfacing veil to resist
corrosive atmosphere.
From power plants to fertilizer industries, paper
mills to refineries to laboratories, sound
electrical design requires an adaptable cable
support system that is reliable. Above all
durability & resistance to corrosion lead to lower
costs during the life of installation.

| Corrosion resistance of resin System
|
|
Two standard composites resin system are
available. For most of the application
isopthlic Polyester fire retardant
[FR-P] is widely used. A vinyl ester
composites fire retardant resin system [FR-VE]
is used where strong acid [ like
hydrochloric acide ] , strong alkalis [
Caustic Soda], organic solvent and
halogenated organic conditions exits. Sumip
fiberglass cable tray incorporates a
synthetic veil on the surface of all
structural shapes which causes a resin rich
layer which enhances corrosion protection.
A abbreviated guide can be provided on request to assist in the selection of the
proper resin system for individual application. |
