- Fibreglass insulated cables
- Working temperature +400 to +550 °C
- High temperature resistance
- Offers lower weight and smaller dimensions
- Fibreglass does not burn
- Flexible material
- The cables with glassfiber insulation show excellent
resistance to high temperatures,
good dielectrical characteristics and good flexibility,
with lower weights and dimensions.
They grant good resistance to mould and chemical
agents.
Glassfiber is fireproof.
Glassfiber is commonly adopted in applications to elevated temperatures,
frequently to
protect insulated cables, with the purpose of increase the duration of the
working time in
case of fire or of occasional increase of temperature.
Despite treatments of impregnation with varnishes or with liquid silicone rubbers,
fiberglass insulated cables (overlapped or braided) are not suitable for applications in
presence
of steam and or oil.
- Outer tin plated copper, stainless steel or galvanized
steel armour
improve mechanical and abrasion features of glassfiber insulated cables.
The cables isolated with glassfiber for high temperature type "R"
could be used
for temperature up to 550°C in accordance with the type of application.
For further
information about "R" glassfiber please contact our Customer Service.

- Overview
- Chemical inertness, non ageing characteristics, excellent
dielectric properties, heat resistance: exceptional properties that permit the use of
cables insulated with these products in many applications where other thermoplastic
material will not be usable.
-
- Heat stability
- Cables insulated with FEP, MFA or PFA can be used in a
wide temperature range; they retain good maechanical properties and flexibility even at
very low temperature (please see details in table below).
- When these products are exposed
to a naked flame, they burn but cease burning as soon as the flame is removed.
-
- Electrical properties
- Excellent electrical properties independent of
temperature or ageing.
-
- Resistance to chemicals
- Fluoropolymers show excellent resistance to corrosive
chemicals and inorganics chemicals, including inorganic bases, oxidizing acids, mineral
acids, metal salt solutions, and peroxides.
- They also exhibit very good resistance to
organic chemicals such as anhydrides, hydrocarbons, funtional aromatics, esters, ketones
and amines.
- Alkalis and alkali base metals such as sodium, potassium
and calcium, that are in a fused or complex dissolved form, may attack the surfaces
causing a brown discolouration.

Silicone rubber insulated cables
- Hot air high resistance
- Low temperature flexibility
- Mechanical and electrical properties
- Physiological properties
- Steam crosslinking
-
-
-
- Heat stability
- Silicone rubber insulated cables show virtually
continuous resistance to
- hot air at temperature up to 180 – 200 °C.
- Higher working
temperature can be achieved by special silicone rubber
- compounds granting good mechanical
properties up to 250°C for several thousand hours
- (for short periods they also withstand
temperature of about 300 °C).
- Silicone rubber insulated cables are not generally
recommended for
- applications exposed to overheated steam.
- Prolonged exposure to steam at
temperatures above 130-140 °C attacks and finally destroys them.
-
- Low temperature flexibility
- Silicone rubber insulated cables retain good electrical,
mechanical properties and
- flexibility even at temperature of -60 °C.
- These
properties are not obtained with the use of special plasticiziers nor at the expense of
heat stability.
- Therefore silicone rubber insulated cables can be exposed to high
- and low
temperatures alternately without being damaged.
- Resistance to chemicals
- silicone rubber is severely attacked by alkalis, acids,
liquid fuels,
- chlorinated hydrocarbons, esters, ketons, and ethers.
- Silicone withstand
aliphatic motor and gear olis well.
- It swell somewhat more in naphthenic oils, while
aromatic oils,
- especially at temperatures exceeding 140°C, usually renders it
unserviceable.
-
- Combustion behaviour
- If a silicone rubber insulated cable is destroyed by
fire,
- insulating silica, instead of electrically conductive carbon, remain.
- So even after
fire cables with special construction can continue to function for a short while.
- Special
silicone rubber compounds can be prepared to obtain LOI value greater than 25%.
-
- Physiological properties
- Cables insulated with most grades of silicone rubber are
physiologically inert.
- Appropriately manifactured cables are thus highly suitable in
medicine,
- pharmacology and for food-contacting applications.
-
- Mechanical properties
- Most important features of standard compounds silicone
rubber (approx. values).
