First, the specifications of the insulation pad (1) according to the voltage level can be divided into 5kv, 10kv, 20kv, 25kv, 35kv
(2) According to the color can be divided into: black insulating rubber pad, red insulating rubber pad, green insulating rubber pad (3) can be divided into thickness according to thickness: 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm.
Insulation pad insulation rules
4mm voltage 5kv 5mm voltage 5kv 6mm voltage 10kv 8mm voltage 10kv 10mm voltage 15kv 12mm voltage 35kv
Second, the insulation pad is used in the conventional configuration:
(1) 5KV insulation pad thickness: 3mm Specific gravity: 5.8KG/m2 Color: red, green, black (2) 10KV insulation pad thickness: 5mm Specific gravity: 9.2KG/m2 Color: red, green, black (3) 15KV Insulation pad thickness: 5mm Specific gravity: 9.2KG/m2 Color: red, green, black (4) 20KV insulation pad thickness: 6mm Specific gravity: 11KG/m2 Color: red, green, black (5) 25KV insulation pad thickness : 8mm Specific gravity: 14.8KG/m2 Color: red, green, black (6) 30KV-35KV Insulation pad thickness: 10mm 12mm Specific gravity: 18.4KG/m2 22 KG/m2 Color: red, green, black
Third, the national standard of insulating rubber pads:
Distribution room voltage 10KV selected 8mm thick power frequency withstand voltage test 10000V 1 minute without breakdown, in the power frequency withstand voltage test 18000V, 20 seconds breakdown.
Distribution room voltage 35KV 10-12mm thick power frequency withstand voltage test 15000V 1 minute without breakdown, in the power frequency withstand voltage test 26000V, 20 seconds breakdown.
Low-voltage selection of power distribution room 5mm thick 500V power frequency withstand voltage test 3500V 1 minute without breakdown, in the power frequency withstand voltage test 10000V, 20 seconds without breakdown.
Fourth, the appearance and specifications of the insulating rubber pad: The depth or height of the unevenness or unevenness of the insulating rubber pad shall not exceed the thickness tolerance of the rubber plate. Within the square meter of the bubble, the air bubble with an area of ​​not more than 1cm2 shall not exceed 5, any two bubbles. The distance between the insulation pads is not less than 40mm, and the depth and length of the insulation pads are not less than 40mm, the edges of the insulation pads are not uniform or the width of the sponge is not more than 10mm, and the length of the insulation pads is not longer than the total length of the rubber plates. 1/10, and does not allow cracks in the insulation pad.
Five, three basic selection criteria for insulating pads:
First of all, don't have a pungent smell. For rubber products, smell is inevitable, but the smell must not be too large. This is as we said at the beginning, the smell is too large to affect the use of personnel. The scented insulating pad is also a direct expression of the excessive amount of secondary rubber added.
Second, look at the degree of stretch, good insulation pads must be flexible. Insulation pads have the function of relieving fatigue in addition to insulation. Pull the insulating pad hard, feel elastic and not break, such an insulating pad can be considered a good product.
Third, pull a pull, fold a fold, there will be no break. A variety of insulating rubber mats that are easily broken are added with recycled rubber in the raw materials. Such insulating mats have poor insulation properties and affect personal safety. The fourth point is also an important point of Zui, to do the pressure level detection. Insulating rubber mats are placed in power stations, which requires that the insulating mats we purchase must meet the specified pressure rating. This cannot be ignored!
Sixth, the use and storage of insulating pads Insulation pads are widely used in substations, power plants, power distribution rooms, laboratory roommates and field live working. Insulating pads should be stored in a dry and ventilated environment, away from heat sources, and more than 20cm away from the ground and walls. Insulating pads should be stored in a dry and ventilated environment, away from heat sources, and more than 20cm away from the ground and walls. Avoid contamination by acids and alkalis and oil. Do not open the air to avoid direct sunlight.
Seven, the production of insulating pads to make insulating rubber pad components: Insulating rubber pads should be made of rubber insulation materials. Insulating rubber mat process and molding: There should be no harmful irregularities on the upper and lower surfaces of the insulating rubber pad. Harmful irregularity refers to one of the following characteristics: defects that damage uniformity and damage the smooth contour of the surface, such as small holes, cracks, local ridges, cuts, inclusions of conductive foreign matter, creases, voids, undulations, and cast marks. . Harmless irregularity refers to the surface irregularities formed during the production process.

Monitoring without network means that mobile phones and cameras can only be seen within a certain range of 5~10 meters.
Therefore, no network and no power is just a gimmick. We must pay attention to distinguish when buying.
Is the Solar Camera easy to use
Jiajie intelligent surveillance camera is very good
Advantages and disadvantages of solar monitoring
Probably.
Generally, offline display has the following two conditions.
One is that the installed 4G card has no traffic and cannot provide network connection for monitoring;
The other is that there is a problem with the signal receiving device, which makes it unable to connect to the network. Therefore, the user can access the APP connected to the monitor to check whether there is still traffic on the 4G card. If there is still traffic, there is a problem with the monitoring; If there is no traffic, the renewal fee can continue to be used.
Which is the best solar Outdoor Camera
It may be that the poor contact of the power plug causes power on, heating and power failure, or it may be that the camera's internal control motherboard fails, causing power on for several minutes and automatic power off protection.
The camera works continuously, and the internal chip may overheat, which also exists in many SLR cameras. Some cameras impose time limits on continuous shooting. Centralized power supply with high-power switching power supply
Disadvantages of camera solar power supply
The main advantages of solar photovoltaic power generation are:
(1) Simple structure, small and light volume;
(2) Easy to install, easy to transport, short construction period, and short time to obtain energy;
(3) It is easy to use and maintain, and can work normally in the temperature range of - 50 ℃~- 65 ℃;
(4) Safe, reliable, noiseless, pollution-free, and absolutely clean (pollution-free);
(5) The advantages of building roofs can be used without the restriction of resource distribution regions; For example, areas without electricity and areas with complex terrain;
(6) The rate of price reduction is fast, and the time for energy repayment may be shortened;
(7) It can be matched with the battery to form an independent power supply, or it can be connected to the grid for power generation.
(8) Local power generation and supply without fuel consumption and transmission lines
The main disadvantages of solar photovoltaic power generation are:
(1) Low solar energy density and large coverage area;
(2) Photovoltaic power generation is intermittent and random;
