2 Energy Division Joints for Polymeric Insulated Cables 72 kv The elastomeric Raychem 72 kv joints are suitable for all polymeric cables and can accommodate various cross-bonding shield break and external grounding arrangements. Quick cable preparation No need for insulation sanding or pencilling Simplified installation No specialists required. A qualified medium-voltage jointer will be trained in one day. Pre-engineered wall thickness All product dimensions are set and checked at the factory before the product is shipped to the field. Time savings Due to short installation time outages are kept to a minimum in repair situations. High reliability The combination of long experience and rigorous testing to international standards leads to high joint reliability. R

Joints for Polymeric Insulated Cables 72 kv Designed for easy jointing The Raychem joint design comprises of a connector that allows even large cross-sections to be jointed and two dual-wall,

The outer sleeve consists of a thick layer of red insulation co-extruded under a black outer conductive layer which acts as the joint screen.

3 Joints for Polymeric Insulated Cables 72 kv Designed for easy jointing The Raychem joint design comprises of a connector that allows even large cross-sections to be jointed and two dual-wall, heat-shrinkable sleeves. A heavy-walled co-extrusion of two layers of red insulation forms the inner sleeve. The outer sleeve consists of a thick layer of red insulation co-extruded under a black outer conductive layer which acts as the joint screen. This is the kit The set of pre-engineered components and the Raychem connector require no special installation tools. After placing the heat-shrinkable components over the cable end, the connector is installed by tightening the special bolts, which shear off cleanly when the correct contact force is reached. Each sleeve in turn is placed over the connector area and shrunk down. Copper shielding mesh and an adhesive-coated outer sleeve for water sealing then complete the joint. Controlled-torque connector The connector design allows cables to be jointed without special tools, heat treatment or filing off after installation. Shear-head bolts ensure a pre-engineered electrical connection. In developing this new connector, much effort was devoted to simplifying the installation steps. Consequently, the key reliability features are engineered into the connector, before it leaves the factory. The outside surface is already machined smooth. The shear-head bolts break off at a predetermined level below the outer surface of the connector, at a defined torque. This ensures the correct contact pressure is reached every time. Oxide-breaking and corrosion prevention is performed by the contact grease inside the connector body. The stable voltage drop provided by this concept has been demonstrated in field installations which closely follow the predictions of long-term load-cycling tests. Comprehensive qualification procedures like IEC and ANSI prove the excellent long-term performance. Electrical stress control A material with stress adjusting characteristics is applied onto the connector and cable screen ends. This heat-shrinkable sleeve incorporates a conductive coating in the connector area which equalizes potential in the manner of a Faraday cage. It extends over the dielectric to accommodate possible insulation shrink-back.

In each case the outer wall of the co-extruded sleeve is heat-shrinkable, while the inner layer is an elastomer held out in an expanded form by the bond to the outer layer.

4 Elastomeric Technology Two dual-wall, heat-shrinkable elastomeric sleeves are at the heart of the joint. Because of the unique elastromeric technology used in their manufacture, these dual-wall sleeves shrink rapidly and deliver pre-engineered, uniform layers of thick insulation. In each case the outer wall of the co-extruded sleeve is heat-shrinkable, while the inner layer is an elastomer held out in an expanded form by the bond to the outer layer. Application of heat to the outer wall causes it to shrink to a pre-determined diameter and simultaneously allows the inner layer to contract, conforming tightly to the joint. In two short steps the installer applies the required insulation thickness and joint screen. When the cable is in service the rubber-like characteristics of the insulation allow the joint to conform to the dimensional changes of the cable insulation during load cycling. Cross-bonding/shield break The use of heat-shrinkable sleeves for stress control, insulation, and screening provides a location for the shield break at the end of the joint. A mastic installed under the heatshrinkable outer sleeve ensures high dielectric strength at this point. The cross-bond can be made without influencing the electrical field in the joint, and does not require any special additional components. Requirements according to IEEE # 575 are fulfilled. Outer sealing The cable oversheath is replaced with a thick-wall heat-shrinkable insulating sleeve, which provides the required dielectric strength and is internally coated with a hot-melt adhesive. The heat of installation causes the adhesive to melt and flow to create an effective water seal and corrosion protection. Grounding leads are sealed by an adhesive coated clip.

The conductors of the cable are connected by a mechanical connector sleeve (1) using torquecontrolled shear-off bolts. A metal shielding clamp (6) on top of the connector provides a smooth interface fit. A metal shielding clamp on top of this connector ensures perfect heat transmission. The fixing rings (5) keep the cable dielectric in position. The Si-rubber cable adaptors (2), accommodating the various cable insulation diameters, will build up the connection area to an almost constant diameter. This makes it possible to cover four cross-section ranges with just one main insulation splice body (3). Cross-section transitions are feasible without any extra components. No extra tooling is needed to push-on the Si-rubber cable adaptors (2) and the Si-rubber splice main body (3) due to its excellent elasticity. Mechanical solderless connector technologies (7) are used to connect metal shields copper wires, metal sheath and CAS. Heat-shrink technologies (8,9) replace the cable serving and the moisture barrier. The joint concept is similar for the shield-break splices, despite the shield continuity. Special sealant components make it possible to use coaxial or double-insulated ground leads, and thereby to utilise the proven heat-shrink technology. All of the above information, including drawings, illustrations and graphic designs, reflects our present understanding and is to the best of our knowledge and belief correct and reliable.

Corona or electrical discharge can ultimately destroy the cable insulation, causing premature failure. Raychem's stress control sleeves have electrical properties that smooth out the electrical field at the end of the cable. This is achieved by the unique resistive and capacitive properties of the heat-shrinkable materials. 80% 90% This is the kit The kit contains a limited number of light-weight components with unlimited shelf life under normal storage conditions. The heat-shrinkable sleeves are extremely versatile, and accommodate a wide range of cable diameters. Three basic kits cover all cable sizes, permitting reduced inventories and an efficient stocking policy. The light weight of the components and limited volume of the kits facilitate safe and easy transportation and handling. All components are included in a single box. The set of pre-engineered components requires no special or expensive tools for installation. Installation involves a simple set of standard procedures with no soldering required. Neither does the termination require filling with oil or compound. Risk of leakage is avoided, and filling and topping-up time on the job site is saved. High-performance material Raychem terminations are made of a specially formulated material with excellent tracking and erosion resistance characteristics. Accelerated and natural weathering tests which are constantly being carried out at Raychem facilities and independent test sites around the world have demonstrated that the terminations are UV and water resistant and perform reliably even when exposed to sudden temperature variations. A Tracking and Erosion Test as per ASTM D2303 showed no tracking. IEC 112 was also conducted with no erosion or tracking observed.
