Heh heh!....LBJ,when she looks at me wi them soft brown gorgeous eyes....i'm her slave!!
Noo,where was I?....right!,considering that aam just a youngin,this tool might have been afore my time,cos every cable used doon thi pits,were armoured...that right Vic?
The abbreviation..."P.I.L.S.D.W.A" ,comes ti mind from my Deputy's training course,[Electrical Engineering ],which stood for .."Paper-insulated,lead-sheathed,double-wire-armoured..",and is a fitting description of the main feed power cables,which used to be covered with pitch-impregnated braided fibre's,loosely referred to as "tarry-toot".[owt wi pitch in was called tarry-toot!This covering was a sod ti peel off,then it was a hacksaw job ti cut through the two layers of wire armour,which was tough stuff!....hacksaw again,ti cut through the lead sheath,then the knife ti cut back the waxed paper insulation which covered each of the three phase conductors.
It was more than a two-hour job,underground,for the electrician to cut a Pummel-end,[plug] off the H.T. cable,and put a new one on,inluding the cold-pour pitch which had to be poured into the plug itself,to provide waterproofing capabilities.
A can still see aal this,clear as a bell,the sparky,mebbe Eddie Hagerty,or ? Cadwallendar..,or Jimmy Haley,peeling aal thi wire armouring back,aal neatly spaced apart,ti put the gland washers and nuts on,before putting the copper pins in,and boxing the job up....and aam harking back ti when aa was 16 yrs aad![1960]
Obviously,the smaller the cable,the armour was appropriately chosen for that cable.
The first time a ever heard of Pyrotenax cable,was maybe in the early 1970's,[maybe a bit earlier],when my Brother was helping his good friend,Jimmy Nicholson,who ran the telly/radio shop in the Market place,alang from Carricks,when Jimmy got the contract to re-wire St. Cuthbert's Church,in Bedlington.
Me Brother brought a small piece doon ti my hoose ti show me,cos he had nivvor seen any either,and he is three years aulder than me,and worked at the auld pit in Bedlington.
A somehoo divvent think it would have complied with the Mines and Quarries act 1954,for underground use,in the presence of a potentially explosive gaseous atmosphere,but that's checkable.
Aal aam saying is,in a pit like Choppington High Pit,where they still had machines,conveyor belts,haulers,which were so ancient,they were there in 1929 when my Father was a 14 year old kid!,aal the aad cabling was still in place,including huge variable resistors,to start the big overhead main and tail hauler,and which used to glow red hot,inside the cage they were enclosed in!This was at the shaft-bottom area,and in freezing cold conditions,so the shaft lads and onsetters used to put pies on top of the resistor pack,keep the brakes on the hauler,and switch the hauler onto low start speed..the motor used to hum like hell,and everybody stood aroond the resistor pack ti feel a bit of heat!!!...nea overload safety interlock!![the pack stood aboot 3feet high,and aboot four feet lang,each resistor being aboot as thick as an average thermos flask.]
Aam really intrigued aboot the Joystripper,cos it was obviously used for thi job it was invented for,but a can honestly say,never in the four pits that aa worked at,ti
my knowledge,mind,that's my disclaimer for being an ignorant aad sod........!...not to my knowledge.!
Somebody please enlighten me,maybe they were used in the workshops,at the pit on bank?
I used ti trail 100 yard lengths of H.T. cable through rough,wet conditions,using two ponies hung on in front of one another,by hanging their tracing chain hooks into the spaces where the gland bolts secured the pummel-end plug onto the cable,and trailing the cable uphill,undulating,around right-angle bends from one roadway into another,and the armouring and tarry-toot covering used ti hold fast,and never pull the plug off the cable-end,they were so securely fitted in place.
Noo flexible rubber armoured coalcutter cables had a different type of armour,which was flexible twisted thin steel wires,surrounding the cores.
Aav got a pair of car jump-leads,which a made in 1972-ish[aroond that time...give a year or two!],from the cores of a buggered cutter cable,and mind...ye couldn't buy a set like them!!...Vic will remember how thick and strong they were!!
In the latter years,from the '70's,at Bates,we had a main feed of 6'600 volts,knocked doon ti 1100 volts ti run thi shearers,and they used ti shear coal at 200 amps continuous!
Noo,if ye saw the cables for the main feeds,we called them "the elephants trunk's",cos they were flexible pvc covered,and aboot six inches thick,and weighed an absoloute TON!!
It was every man a yard apart when it came to carrying any of that cable in to the face,periodically,as the face advanced.
