RB-JT119P

Medium voltage cable joint fire and explosion box

Product specifications：

Height 190mm, length 950mm (optional extension accessories extend to 1400mm)

Product introduction：

It is applied to intermediate joint of medium voltage cable to prevent explosion shock wave damage and flame flame flame from fire caused by single-phase ground-loss due to joint fault or two-phase short-circuit explosion after single-phase ground-loss, in order to protect the adjacent many other cables, to avoid expanding the scope of the accident and avoid causing indirect harm, to minimize the accident losses, and to reduce the accidents caused by the long-term soaking water and dampness of the cable joints and the operating environment, the utility model provides effective, safe and reliable guarantee for the operation of power cables.

Installation Notes

1.Anti-explosion pressure relief: stainless steel shell, can withstand the instant explosion impact, and innovative pressure relief channel along both ends of the cable to release the explosion shock wave and high temperature flame, to avoid injury to the surrounding cable
2.Fire Protection: the stainless steel shell effectively guarantees the integrity and fire protection of the shell after explosion, the inside of the intact shell can not produce flame because of no air circulation, and the inside and both ends of the box are provided with fire-proof expansion materials,effectively prevent the spread of fire
3.Reliable product seal: effectively avoid the long-term moisture of the cable joint bubble water, reduce the accident rate caused by the operating environment
4.Durability: corrosion resistance, resistance to external shock, high temperature and low temperature resistance, service life≥10 years

	Performance indicators	Typical values
1	Cable clamping performance test	The cable with diameter of 69 mm was subjected to 1380N pull force for 6 hours without displacement
2	Temperature measurement	The maximum surface temperature of the explosion-proof box is 100℃
3	Impact test	The metal shell can bear the impact energy of 7J without
4	Dielectric strength test for insulation	Applied 21KV voltage between phase and ground，lasted 60S, no breakdown
5	Shell protection rating	IP68
6	Heat and cold resistance test	No significant change

6~ 35KV each section (25 ~ 400MM2) cable intermediate joint fire, explosion-proof, waterproof protection when the joint failure,the loss is effectively controlled in the fire-proof explosion-proof box device
