CORROSION-FREE
ELECTRICALLY NON-CONDUCTIVE
GUY WIRE
Its makers claim it is stronger than steel for the same cross-sectional area, light weight, corrosion-free and electrically non-conducting. Furthermore, unlike steel guy wire, it shows virtually no elongation with the passing of time.

Called "DEBEGLASS WIRE", this product is in use in many applications throughout Australia and the world. Its corrosion-free, non-conductive, non-magnetic characteristics make it eminently suited to use in supporting and guying applications within the marine environment as well as throughout continental Australia. Supporting high frequency radio antennas and guying their towers, where a electrically conductive guys would adversely effect the antenna's radiation pattern, is a common application for Debeglass Wire. Its surface characteristics also have the effect of reducing the adhesion of marine organisms.

Manufactured in Japan, Debeglass Wire uses relatively new technology to bind high tensile fibreglass yarn into a compact circular cross-section. The bound yarn is then sheathed in a special UV stabilised PVC.

Three sizes are normally keep in stock by GFS Electronics, 4mm, 5mm and 6mm outside diameters. Tensile strengths are shown in the table below. Stocks of the larger 8mm, 10mm and 12mm Debeglass Wire is available ex-Japan, with deliveries of generally six to eight weeks. GFS Electronics also normally keep stocks of "DEBECLIP" terminators for the various Debeglass Wire sizes.

The yield tensile strength of the thinnest 4mm diameter DEBEGLASS wire is 430 Kg. This is stronger than steel wire having the same diameter. Moreover the weight is some 30% less than the steel.

Debeglass has established itself as an important non-conductive antenna stay and catenary support product. It is especially suited to these uses by virtue of its unique combination of properties - low elongation, high strength to cross sectional area, high strength to weight ratio, excellent resistance to UV degradation and environmental attack, high fatigue life and excellent electrical properties. It is virtually maintenance free and much easier to handle and terminate than other similar products.

These properties give Debeglass Wire many advantages over other stay materials. For example it obviates the need for awkward and expensive combinations of metallic wire and insulators.

Although Debeglass' smooth PVC sheath is primarily for the physical protection of the high strength continuous filament fibreglass core, it contributes substantially to the electrical properties by (a) providing a completely water tight skin preventing moisture penetrating the core, and (b) presenting a surface which is easily washed with clean water so that pollution is controlled under normal conditions by the washing action of rain. Under conditions of heavy pollution where surface contamination is regarded as severe, the smooth PVC surface can be cleaned by direct washing with clean water

Since the ability of a Guy Wire to resist deterioration on long and continuous exposure is of the upmost importance, Debeglass wire has been developed from two materials which both have a high level of mechanical toughness and are virtually inert chemically. Its load bearing fibres are protected from wind blown sand and grit by the PVC sheath, and both components have outstanding resistance to the corrosive actions of most acids and solvents.

Debeglass is immune to severe icing since ice cannot "key-on" to the smooth outer sheath, and provided the stays are correctly tensioned, any ice that does form is quickly removed by normal wind vibrations.

TERMINATORS

Termination of Debeglass in the field is an extremely simple operation without the need for glue, sealant, or special tools, just a screwdriver or spanner, depending on the Debeglass size used. One standard size Debeclip fits 4, 5 and 6 mm Debeglass. However separate Debeclips are required for 8, 10 and 12 mm Debeglass. These large Debeclips are a special Stainless Steel 'D' Clamp (wire rope grip) type terminator, three are used per termination. Details on termination options are shown HERE.
