Abstract: Electrical wire conductors which project from two insulated cable end portions are received in tubular electrical connectors electrostatically precoated with electrical insulating material. Each precoated connector end portion respectively abuts and is sealed in engagement with insulation on an associated cable end portion. The precoated connectors are crimped into gripping engagement with the wire conductors therein to form a basic electrical splice. A tubular inner melt liner and a tubular outer sleeve of thermoplastic electrical insulating material are arranged in generally coaxially surrounding relation with the basic splice. Heat is applied to substantially simultaneously melt the inner liner and shrink the outer sleeve to encapsulate the basic splice.
