Heat shrinkable power cable accessories with small size, light weight, reliable performance, adaptability, easy installation features. Power cables for indoor, outdoor terminal and intermediate fittings.

Our heat shrinkable power cable accessories by the State Ministry of Power Industry Quality Inspection Center electrical equipment tested to meet the requirements of GB8114-95 standard.

Heat shrinkable power cable accessories line includes: 1KV rubber, cross-linked cable terminal and middle joints; 10KV XLPE cable terminal and middle joints; 10KV oil-immersed cable terminal and middle joints; 35KV XLPE cable terminal.
A heat shrinkable power cable accessories used to allow ambient temperature range: -40 ℃ - +70

heat shrinkable power cable accessories installed - like requirements:
1 Oil crosslinking profile cable connector lead from start to close, must be continuous construction time to complete. To avoid damp, 10KV and below the cable heat faint within 6 hours should be produced.
2 Cable Terminal and intermediate fittings in the production process must be kept clean and dry the following sections: profile of lead and turnkey cable, insulated wire part of the paper; construction with insulating materials, tools and instruments; the hands of construction workers should always be kept clean.

Preparing for Installation:
1 Before making the first cable, tools required to prepare complete, construction personnel should be familiar with the use of various tools and instruments, inspection and precautions.
2 before making heat shrinkable cable head, should be prepared to complete the required heat-shrinkable material and supporting materials, check the material is qualified, according to the cable construction, specifications, used to determine the suitability of heat-shrinkable material.
3 before the first production of heat shrinkable cable, on-site preparatory work should be done as follows:
3.1 the construction site well lit, lighting devices must conform to safety regulations.
3.2 the construction site should be kept clean and dry.
3.3 The erection of protective outdoor construction should be shed, should be set high above the ground table.
3.4 When near live equipment should be safety measures.
3.5 the construction site shall comply with fire safety requirements, on-site fire-fighting equipment should use a blowtorch should be noted that fire and explosion.

Heat Shrinkage technical requirements:
1 Recommended use propane heat tool gun, yellow flame temperature is moderate, heat a large area, high petrol blue flame temperature, away from the material should be noted that due to control temperature, to avoid burning.
2 All materials were all heat-shrinkable polymer materials produced by a special process, the temperature reaches 110 ℃ -130 ℃ when the material starts to contract, more than 50% shrinkage. Material at 140 ℃ short time will not be affected, but for prolonged overheating will damage the local or even burned material, affecting material properties.
3 when the flames began to shrink tube to slowly close, move around to ensure uniform radial contraction, then slowly extend, shrink toward the direction of the flame to warm pipes, help shrink evenly. Follow the recommended installation location and direction of the initial contraction, contraction from bottom to top will help rule out gas and enhanced sealing.
4 To ensure that the heat-shrinkable material and layering of materials and the close integration between the adhesive strength, set into each tube before being layering parts and adhesive sealing sections should be preheated, and then wash with clean paper.
Remove carbon deposits flame smoke, so that good contact between layers.
5 contraction completed pipe should be smooth without wrinkles, can clearly see the outline of its original structure. Sealing parts out of a small amount of sealant that seals sound.

Install the conditions and requirements:
1 Shrink accessories shall be installed at ambient temperatures above 0 ℃, relative humidity below 70%. Surface of the insulation to avoid condensation damp, low ambient temperature, humidity is too large to be taken remedial measures.
2 Do not arbitrarily cut heat shrink tube.
3 Shrink sealing contact with metal parts, accessories and parts (such as lead pack, terminal) to carefully roughened and cleaned with a cleaning agent.
4 in place at the end of the cable, the dislocation cores should be avoided, so as not to affect the sealing effect.
5 rain and fog weather construction can not be found cable water, damp, remedial measures should be taken.
6 the construction process, the cable sheath and insulation damage is strictly prohibited.
7 shrink the middle connector is not fully cooled down, not allowed to move the cable.
