A multi-layer heat-shrinkable tubular sleeve () comprises an outer layer () and an inner layer (). The outer layer () is arranged around the inner layer (). The outer layer () comprises a partially crystalline thermoplastic material with a major part of partially crystalline thermoplastic material with a crystallinity of more than 60%. The inner layer () comprises a partially crystalline thermoplastic material or an elastomeric material.

Multi-layer heat shrinkable tubular sleeve

The present invention provides a high voltage connector arrangement comprising an elongate electrically insulated module, which may be an insulated and screened surge arrester module, and an insulated connector for connecting the module to electrical equipment, which may be switchgear. The arrangement may be such that components of the module are protected from excess current flow therethrough, or the electrical field at the connector end of the conductive layer screen of the module is reduced. In an embodiment, the arrangement can achieve both of these results. The protection of the module is achieved by placing an electrode of the module within an insulated, and advantageously screened, arm of the connector adjacent the end of the conductive layer screen of the module. The electrode may comprise the electrode at one end of the module or may be spaced therefrom, for example by a component of the module. The electrical field stress may be reduced by suitable shaping of the electrode at the end of the conductive layer screen of the module.
