On the left is a pack of 1960's 'pots'. These comprise [surprisingly] of a brass pot specific to the size of the cable diameter. On the box are shown 2 little 'spots'. These attach to the plastic sleeving below the level of the 'biscuit' [disc with holes in it]
The cable is stripped and the pot screwed on until the sheath just enters the pot base. The cores are pulled straight and the biscuit, spots and sleeve attached . The whole lot is then slid down until the pot rim is reached. This serves to fan out the cores. The biscuit assembly is then withdrawn slightly and the pot filled with 'compound'.The biscuit is then fitted and compressed/crimped to the pot. After termination of the other end the whole assembly is tested for earth leakage at 500v for our 240 / 415v systems. Note; it has actually taken longer to type this than it does to terminate a 2 core cable!!
The 2 yellow boxes contain a later version of the same items. Sizes used to be measured in 1000th of an inch and number of cores; soa 263/3 was 263/1000" outer sheath diameter of a 3 core cable.
The remainder shows a old style blown-up temination [unfortunately the bits are in the wrong order. The 3 part gland fits before the pot and seals to it by compressing the 'olive' between the 2 parts of the gland body. note that the sleeve is now fitted with the 'spots' attached to the sleeving. This sleeving is passed through the biscuit from the rear after being cut in half. Cleanliness is paramount in this type of termination, but done correctly the assembly is 'fire rated'. Get it wrong though and....
