The incredible shrinking world
18/07/2016 15:50:05 NewsCable News

Porthcurno Bay, CornwallIf you are ever down near Land’s End, you could do worse than visiting The Porthcurno Telegraph Museum, located in the small eponymous coastal village. This was the point at which many submarine telegraph cables came ashore. The museum, which opened in May 1998, is housed in the former telegraph facility. Above the beach was a small building, where the operator would send and receive messages to and from the far reaches of the Empire.

Transatlantic cables of the 19th century consisted of an outer layer of iron and later steel wire, wrapping India rubber, under which was a layer of gutta-percha, which surrounded a multi-stranded copper wire at the core. The portions closest to each shore landing had additional protective armor wires. Gutta-percha, a natural polymer similar to rubber, had nearly ideal properties for insulating submarine cables, with the exception of a rather high dielectric constant which made cable capacitance high. Gutta-percha was not replaced as a cable insulation until polyethylene was introduced in the 1930s.

Each cable carried but a single message at a time. For the Empire. The British Empire. The biggest Empire the world has ever known until now. One line of communication for India, one for Canada and one for Australia. One. If you only have one line, what data is sent, and what isn’t?

Even so, it was the envy of the world. This was the biggest and the most important communication hub in the world. Until then, the only way to send messages was by Packet Ships, and they could take months.

This is an incredible concept in this day and age of mass, constant communication, most of which is ephemeral and inconsequential, after all, who really needs to know what you are having for lunch? One thing is certain though. Technical development and Innovation is snowballing, driven by ever increasing speeds and levels of communication. But we have to keep up. There is no point of talking if nobody is listening. We at Aerco Ltd listen. Call us with your requirements. We will tell you if there is a standard product that meets them, and if not, we will guide you through the design process to produce one that does, advising you of the pitfalls, and coming up with an affordable solution within a realistic time scale.

Modern undersea cables are constructed of armoured fibre optics, sending data at the speed of light, and we rush head long into the future, surfing on the wave of ever increasing speeds and levels of communications.

Aerco Ltd are currently looking into entering the Fibre Optic world, and hope to be making announcements in the near future, so, if you have any requirements regarding Fibre, give us a call. We shall endeavour to treat them with the level of professionalism you have come to expect of us.

And the museum? Start with a visit to their website at www.telegraphmuseum.org and as for the world, it may be getting smaller, but I wouldn’t want the job of painting it!

On the 4th May 1982, HMS Sheffield, a Type 42 Guided Missile Destroyer being deployed in The Falklands Conflict, was attacked by two Argentinian Super Etendard aircraft armed with Exocet Anti-Ship Missiles. The missiles scored a direct hit, but whether or not they exploded is open to conjecture and debate. However, what is beyond debate is that damage caused by the missile impact severed the high-pressure fire main on board, and the resultant fire, caused by burning rocket propellant, ignited diesel oil from the ready-use tanks in the engine room, and other inflammable materials used in the ship's construction. Twenty crew lost their lives, and the fires continued to burn unchecked for a number of days after the ship was abandoned. The ship finally floundered on the 10th May.

On the 18th November 1987, a lit match dropped on an escalator at Kings Cross Tube Station resulted in a fire. Thirty-one people, including London Fire Brigade officers, died and 100 people were taken to hospital, 19 with serious injuries.

Although there were other major contributing factors in both cases, the use of PVC insulated cable is both situations did not help, and probably made bad things worse.

When PVC burns, contained within the smoke is Hydrogen Chloride gas. When this condenses with water vapour, or onto a wet surface, Hydrochloric Acid is formed. On the Sheffield, this acid burnt through the printed circuits on the Fire Fighting equipment, allowing the fire to get out of control, and at Kings Cross, people in poorly ventilated areas, trying to escape, choking and suffocating in the dense acrid smoke, were unable to safely evacuate.

We learn by our mistakes, and new materials were sought that could replace PVC, but without the harmful effects of acidic smoke. Hence the introduction of Zero Halogen cable, which is produced without using any of the Halogen group of elements, Florine, Bromine, Iodine and Astatine, as well as the Chlorine found in PVC. Materials within the Polyethylene family have always been favourite, as well as Silicone, but recently a new weapon has been added to the arsenal.

Alpha Wire Inc, for whom Aerco Ltd are Premier Distributors in the UK, have recently introduced the EcoGen range of cables. EcoGen products contain no halogens, phthalates, or heavy metals. The mPPE thermoplastic insulation and jacketing can also be easily recycled. They meet RoHS and WEEE requirements for the elimination of hazardous substances and recyclability.

If you have a need or desire to move away from using PVC insulation, contact us at Aerco Ltd, and we shall be happy to guide you to the right product for your requirements.
